Unity is crashing on Windows 10

Unity was working perfectly fine on my Windows 10 until I installed the recent update (2018.2.16f1). Now I get this error (running Unity directly):

Actually, Unity just doesn't open. I had to find this info from the event viewer. Anyone else have this problem?

What I tried so far:
1. Competely unintall and delete the Unity folder, then re-install.
2. Reboot (of course).
3. File system permissions (again, it was working on the previous version just fine).
4. Create a brand new project from scratch as a test. Unity still crashes.
5. Firewall turned off.
6. Tried running as Administrator.
7. Updating my graphics card driver.
8. Making sure the registry is completely removed at uninstall.
9. Installing the previous version as a test (now no versions work at all it seems).

 

Please make sure that you submit a bug report. You can find the tool in the installed Unity folder.

 

Ok, thanks.

 

Ok, I figured this out on my own. Unity definitely has a bug, but I think it is centered around Citrix display adapters. I think what happened is that Citrix Workspace updated itself to 18.10.0.20023 during the same time Unity updated (or just before perhaps). When I launched Unity it crashed doing something with the graphics (according to the logs I reviewed). As soon as I deleted the Citrix display adapter that gets installed Unity started working again. It seems like Unity is enumerating the display adapters and expecting certain valid types, and not virtual ones. Anyhow, it’s a good thing I no longer need Citrix for my support job at the moment, or any time soon. Hopefully this helps anyone else who might fall into the same issue. Cheers.

 

Thank you @jamesnw !! I tried several options but nothing worked until I came across this thread.
Uninstalled Citrix Receiver and restart system.. worked for me!
***Unity version: 2018.2.3f1

 

Did Citrix break Unity games yet again, or is this the same issue from 2018? See thread below for Unity versions with the fix for Citrix issues.

The issue was specifically with the old version of Unity: 2018.2.3f1. Not an issue with later versions, we are using the old version to support an app and we are looking into undegrading to the latest version. Thanks for your response!

 

You can probably move to 2018.2.21 (the latest 2018.2.x) with relatively little risk of things breaking. 2018.2.21 has the fix for the citrix workspace issue, but doesn't have the new prefab system, new Physx version, and new terrain system changes which all came in 2018.3. Just a suggestion if you're really just looking to address this specific problem.
