As you can see it didn’t help

It all started with how I converted the project to ump, and then back to a normal project

Such errors occurred before, but as soon as I changed something in the script, all the errors disappeared. now it doesn’t work
Please help, I have been working on the game for 3 months.

Since there is a mention of Visual Scripting near the end, try removing the Visual Scripting package from Package Manager if you aren‘t using it.

How to troubleshoot build failures:

First, make a blank project with a single blank scene and prove that it builds successfully.

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

Until you can build a blank project to the target platform, don’t fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

Android build not building:

Recently (circa July 2022) there have been reports of Unity’s installer failing to install the Android Tools.

Can't build for Android

Latest Hub 3.2.0 in combination with Unity 2021.3.6 can't build for Android because there is a missing Tools folder inside *Editor\Data\PlaybackEngines\AndroidPlayer* so Unity can't find gradle. That folder is simply not created during the installation. The workaround is to copy the whole Tools folder from the previous Unity version or if you don't have the previous version then do what [mention|1j+oWeNEPCI6ejbN15sncw==] says in the post below .

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

.AAB Build Targeting API Level 33 on Unity 2021.3.8 with JDK 1.8.

Hey, coincidentally I just upgraded to Android SDK31 today… why not wait until nearly the last minute? It was a wild ride, took most of the day. Let me tell you what I did, what I found. First of all, I’m using Unity2020.3.41 (hereinafter referred to Unity*) because that’s all the further I need to go forward right now. I found that Unity* only accepts up to SDK30.0.3 tools, but will build using those tools and SDK31. Next I found that Android Studio will not install anything except Android …

Android Gradle errors and other related stuff:

Unity Gradle bug... please help

Fix:

Lost progress / project / work / stuff disappeared in Unity.

This article is to help you when you have lost significant progress or work in your Unity project.

It is designed to give you avenues of discovery and investigation.

It is NOT a guarantee of restoring your lost work. It is NOT a substitute for proper IT / Data security procedures.

To decide which parts are applicable to you, look for major bolded headings.

EVERYTHING IS GONE, YOU CANNOT OPEN THE PROJECT

Your project probably is still on your computer. Try a computer-wide search for some unique filenames that you know are in the project you think is gone.

To start your search, one common file to all Unity projects is named ProjectSettings.asset

Some things that might have happened:

• you are not opening the project that you think you are
• you are in the correct project but not opening the same scene you had open before
• you dragged the project (or part of it) into the trash (intentionally or inadvertently)
• you moved the project (or part of it) somewhere else (intentionally or inadvertently)
• an overly-aggressive antivirus solution quarantined it because it saw code being compiled in there
• you’re using a directory sync like OneDrive or Dropbox… NEVER USE THESE SERVICES WITH UNITY!
• something else??

As I said, it’s probably still all on your system to be found if you look in the right places.

A typical Unity project will have at a minimum the following folders:

ProjectSettings\
Packages\```

**EVERYTHING IS PRESENT BUT MY SCENE WINDOW IS BLANK**

Close Unity and make a full project backup RIGHT NOW. Do not do ANYTHING else until you back it up 100%.

Ideally copy that backup to another computer, or back it up to another external hard drive entirely. This is just basic data processing best practices during data recovery operations.

If you can see all the files and folders of your project, make sure you are opening the scene file you were working in.

Once you have opened the scene, look in the hierarchy window, select an object and move the mouse over the Scene window and press F to focus that object.

Additional notes:

- ALWAYS use proper industrial grade source control (see below)
- NEVER use Dropbox or any file sync mechanism in Unity.
- NEVER move files within your project, except by doing it within Unity
- ALWAYS be sure you are fully backed up before upgrading Unity

**SCRIPTS OR ASSETS ARE MISSING OR BLANK**

Some info about Missing script warnings, broken prefabs, GUIDs, renaming GUIDs, etc:

https://discussions.unity.com/t/836322/2
https://discussions.unity.com/t/815173/7
https://discussions.unity.com/t/815173/9

EVERYTHING in Unity is connected to the above GUID, which is stored ONLY in the metafile, and hence why the metafiles ALWAYS MUST be source-controlled.

**When Renaming**: It is super-easy to inadvertently change the GUID by renaming outside of Unity. Don't do that. Instead:

- close Visual Studio (important!)
- rename the file(s) in Unity
- in Unity do Assets -> Open C# Project to reopen Visual Studio
- now rename the actual classes, and MAKE SURE THE FILE NAMES DO NOT CHANGE!

If you are NOT using source control while you do this, renaming files is an EXTREMELY dangerous process. Use source control at all times so that you can trivially revert if you miss a critical step and damage your project.

**UNITY CRASHES / FREEZES WHEN I OPEN MY PROJECT**

You must isolate if there is something wrong with your Unity installation, something wrong with your project, or perhaps just a corrupted import or asset database.

First, ALWAYS back your project up. Then try deleting the ```Library/``` and ```Temp/``` folders that are within your project, the directories that are peers to the ```Assets``` and ```ProjectSettings``` folders.

If that doesn't work it is time to bisect. Make a new empty project and get Unity to open that. If you cannot then it is time to fix your Unity installation, either by fully reinstalling or verifying it with the hub.

Once you have an empty project open, begin copying over your project. Try the entire thing. If it crashes, try half of the project, then the other half, etc.

As always, if you're using Windows, another thing to try is to simply reboot the system. This often fixes typical Windows issues related to locked files and locked directories.

**ISSUES RELATED TO UPGRADING PROJECTS (eg, changing to a higher Unity version)**

Upgrading to a later version of Unity is a one-way process. Any project that has been updated should NEVER be reverted to an earlier version of Unity because this is expressly not supported by Unity. Doing so exposes your project to internal inconsistencies and breakage that may actually be impossible to repair.

If you want to upgrade to a newer version of Unity, do not even consider it until you have placed your project fully under proper source control. This goes double or triple for non-LTS (Tech Stream) versions of Unity3D, which can be extremely unstable compared with LTS.

Once you have source-controlled your project then you may attempt a Unity upgrade. Immediately after any attempted upgrade you should try to view as much of your project as possible, with a mind to looking for broken animations or materials or any other scripting errors or runtime issues.

After an upgrade you should ALWAYS build to all targets you contemplate supporting: iOS and Android can be particularly finicky, and of course any third party libraries you use must also "play nice" with the new version of Unity. Since you didn't write the third party library, it is up to you to vet it against the new version to make sure it still works.

If there are issues in your testing after upgrading Unity, ABANDON the upgrade, revert your project in source control and be back where you were pre-upgrade with the earlier version of Unity.

Obviously the less you test after the upgrade the more chance you will have of an undiscovered critical issue.

This risk of upgrading is entirely on you and must be considered whenever you contemplate a Unity version upgrade.

Do not upgrade "just for fun" or you may become very unhappy.

**PROPERLY CONFIGURING AND USING ENTERPRISE SOURCE CONTROL**

I'm sorry you've had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

I usually make a separate repository for each game, but I have some repositories with a bunch of smaller test games.

Here is how I use git in one of my games, Jetpack Kurt:

Setting up an appropriate .gitignore file for Unity3D:

Generally the ONLY folders you should ever source control are:

Assets/
ProjectSettings/
Packages/

NEVER source control Library/ or Temp/ or Logs/
NEVER source control anything from Visual Studio (.vs, .csproj, none of that noise)

Setting git up with Unity (includes above .gitignore concepts):

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It's simply ridiculous not to back up.

If you plan on joining the software industry, you will be required and expected to know how to use source control.

@CodeSmile

Since there is a mention of Visual Scripting at the end, try removing the Visual Scripting package from your package manager if you don’t use it.

Thanks for the advice, but unfortunately it didn’t help.

but the error has changed

I tried many ways, but nothing really helped.
The only thing that helped me was the transition to the version 2020.
Thanks to everyone who tried to help me.
