    After closing the editor, it won't start again. The Unity splash screen shows, and then goes back to the hub.

    After rebooting windows, everything will work fine, until I close the editor. Then it will not open any projects in the a14 editor until I reboot my computer.

    I think there is some kind of event not firing correctly when starting the editor for the second time. If I wipe my library folder, it does not get recreated (until reboot) either.

    I'm using a personal license, and didn't have this issue on any earlier 2020.1 alpha up to a12.

    I'm on Unity Hub 2.1.3. I just uninstalled it and downloaded the installer from the website which also installed 2.1.3, so it must be the latest. The problem still persists.

    Edit
    Fixed by deleting my "C:\ProgramData\Unity" folder. Not recommended.

    This problem probably caused by latest Nvidia drivers. Previous driver will work fine, probably (Studio driver 441.12 is working fine for me, 441.28 - crash & project won't load). Just don't tweak "Bounces" parameter for ray-traced GI, it will always crash no matter the driver.

    Yeah that's a different issue, I experienced that too a while ago.

    You probably needed to delete the Unity_lic.ulf file only, not the entire directory.

    Pass the word if you see other people having the problem, please. I'm tired of posting this.

    Renew your license. There is a problem with licenses becomming invalid. The worst about it is the you will only see this in the log file of the editor.
    Unity needs to add a more user friendly error feedback than just closing the editor and reopening the hub.

    The hub said my license was valid. The first thing I tried was to return my license and activate a new one, which didn't help. That's when I deleted the programdata folder because I noticed it contained a few cache directories.
