I tried loading my project and scene and this icon came up.
When i try pressing these options none of them work (neither load default or revert factory). This only occurs in the project i’m trying to work on. If i load a different one or make a new one it doesn’t do it. Anyone know what to do because I want to keep working on my game.
Now I have solution for this problem. You have to use higher version of unity to come out of this error.
At present your project initially created in higher version and same project you are trying to opening it on lower version compare to you have created.
Backup (Copy/Paste) your Project Settings file somewhere else. I just dragged mine to my desktop. It’s a good idea to backup the entire project at this point too.
Delete the Project Settings folder from your project
Open the project
Right click the Assets folder in the Project window
‘Reimport All’
Go to the root folder again
Delete the Project Settings folder again
Paste your old project settings into the root folder
I found the problem as well as a solution.
I checked the folder that contained my project and found out it belong to root so I Unity3d could not access it, just change the permissions of the folder.
In linux
My solution was to change where I was creating project. The folder I was using had all permissions and was not read only, but it didn’t work. So I just used a different folder on my other drive.
Та же проблема. Помогло копирование содержимого из папки ProjectSettings рабочего проекта в ту же папку нерабочего.
The same problem. Copying content of ProjectSettings folder from working project to the same folder of non working worked for me.
Resolved IT
Create a new Project
go to the file location and copy
‘project’/Library/CurrentLayout-default.dwlt
Paste this file into your original projects …librarry/… path
It worked for me.
I get the same Error, but when creating a new project. I completely removed Unity and reinstalled. It fixed the problem for three days, then it happened again. Once it happens, I can’t even open some of my old projects.
