So i have installed unity 5, after trying to open in it just opens the load screen and sits there. I tired turning off windows firewall, Malwarebytes but still not opening up. On the task manager says using 0 CPU, and disk. What can i do to get unity to open up?

Im using a windows 10 build.

I’ve got the same problem and after a little research I came to an answear.
Before anything, backup your projects.
Open any folder and go to %AppData%
Then, a “Roaming” folder will open. Search for Unity and delete this folder.
Go up one folder (AppData) and do the same to Local/Unity and LocalLow/Unity.
Hope it works.

I had the same problem. But the solution which delete Unity AppData didn’t work for me. And Reinstall also didn’t work.

Eventually I find a resolution by accident. And I dont’t know which step exactly work, you can try these one by one:

  1. close firewall
  2. close network
  3. open Unity in offline mode
  4. If it get work and won’t stuck on loading screen, open project
  5. recover network and firewall
  6. you can open project as usually afterwards

(If it still don’t work for you, and I found it have some useful log file to check what problem cause this: C:\Users\Administrator\AppData\Local\Unity\Editor)

For me it worked by deleting the c:\Users<…>\AppData\Local\Unity\cache folder.

I work behind a proxy. Unity breaks when going in and out of a proxy. I use 3ds Max, Adobe products, and yes, Unreal Engine, and none of them have the same issue. They all work fine both at work and at home. Only Unity breaks. I have extensive emails with Unity’s customer service and they are useless when it comes to this issue. They just tell you “there’s a connection problem” which doesn’t help.

Here’s what I do:

If I’m working from home (outside the firewall):

  1. Windows Key > Start typing “environment” > Open “Edit the system environment variable”
  2. Select “Environment Variables”
  3. Delete the HTTP_PROXY and HTTPS_PROXY (I recommend taking a screen grab before deleting them as you’ll need them when you go back to work).
  4. Open Internet Explorer > Internet Options > Connections Tab > LAN Settings
  5. Uncheck both Automatically detect settings and Use automatic configuration script
  6. (Not sure if it’s necessary) Restart computer

When I go back to work, I do the reverse:

  1. Check the Use Automatic Configuration Script
  2. Add the HTTP_PROXY and HTTPS_PROXY back to Environment Variables
  3. Restart computer

Cheers.

I’m having this issue with Unity 2017.3.0f3.
I’ve tried removing the Unity folders in Appdata and restarting, removing the project folder and recreating, uninstalling and reinstalling unity, all with no luck.

It always hangs loading com.unity.ads@2.0.3\Editor\Resources\Editor\landscape.jpg for about 5 minutes, then loads and sits with a white screen.

It actually worked fine last week until I tried to run the Google ARCore example project. It froze during the build process and hasn’t worked since.

I had to turn off my VPN

All other projects or new projects opens, but my current project don’t. So my problem about project itself, but How do I solve this?

I just restarted my computer and it worked

I am not running neither VPN nor my connection is bad.
Still, it takes up to 15 minutes for the hub to be loaded.
I just don’t understand why. It’s just a simple web page, can’t they fix this…

I also had this issue. Instead of trying to open a project through Unity Hub, I just directly launched Unity Editor through its executive file in Program Files\Unity\Hub\Editor\(version)\Editor\Unity.exe, and then opened my project. It finally loaded.

Before doing this, for my confidence I also had deleted all cache in Unity folders inside Roaming, Local and LocalLow folders. Not sure whether the cache deletion was really needed though.
