Unity gets stuck on white loading screen on startup?

Splash screen comes and goes, then it shows a white window with a little blue loading bar and no text. It loads to completion then hangs.

Whats goin’ on?

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.

The fix for me was turning off my VPN software.
I tested it a few times and every time when the VPN software was running (and connected) Unity opened slow(er) and got stuck on the white screen… (crash?)
When the VPN was off, everything acted like normal.

Same pls help

same. No idea how to fix, though.

Restart your computer first, it worked for me.

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)

Try opening/running it as admin, worked for me.

Right click the program and choose run as administrator.

in most cases, this is due to a very slow internet connection.
or probably has some problem with you internet service provider.

I disconnected wifi and unity work offline . Reconnected → Click “Sign In” → Works.

This happened to me on Unity 2018.1.1f1, but I think it’s caused by very little bandwidth. I was uploading a large file at the time. Once I stopped that upload, Unity started normally.

Hi,

Doing below 3 steps solved issue at my end:

  1. Open LAN Settings by clicking the pointed LAN settings button 123163-lan-settings.png as shown in image.
  2. And then check “Use proxy server for your LAN” toggle.
  3. Then restart Unity.

Thanks,
Nitish

I cleared out the files (only the deleteable ones) in \AppData\Local\Temp, and it worked as well. Not exactly sure the reasoning behind this.

You need to check the remaining RAM size on your machine:
You should terminate any unnecessary other running programs.

I solve this problem by go to Properties click on Compatibility and click on Run compatibility troubleshooter choose Try Recommended Settings and test the program then I save settings. and now working pretty good :slight_smile:

FIXED: i had the same issue. I went to C:\Users\USERNAME\AppData\Local\unityhub-updater and ran the installer from there. That reinstalled the unity hub and everything worked normally. All my projects were there as well. You may have to sign in again tho. hope this helps someone!

I’m using Windows 10 and this happened after an update.

I tried everything and more than everything, nothing worked, so I found that I could easily revert the update. It’s now working fine!
