When I try to open unity or new project from unity hub, this window pops up.
I have updated my license, reinstalled hub multiple times but still the same error.
I can not open unity 2019 without hub. Tried opening it directly through project scene but no result.
I am using unity 2019.2.15
same here,
3 hours now trying everythings but not noway
even with an empty new project, unity crash
ok, seem’s solved for me
had to delete everything concerning unity in AppData/ before reinstalling unity alone, without the hub…
i think i will stay away from the hub for a while now
I tried your method and its working.
Thank you, mfleurent

Well Quitting Unity Hub from system tray… and reopening unity worked for me… i don’t know why that simple in my case…
Where is the System tray?
lol thats the thing on the bottom right (by default ) on windows… that little up arrow
Thanks mate,worked for me just fine
I don’t know why my case is so hard, but I’m having the same issue for everything. One day it was working and the next all the sudden I can’t open up any project or create one without this blank error screen popping up each time I try to open or create a project. And when I try to open a project it says: “Project path does not exist. (location of file)”. I really need help… I’ve been trying at this for a month or two now and probably over 20 hours of trying to fix it. If anyone knows where every single unity file is, maybe I can try deleting all of them so I can do a FULL re-install. Once again please help, Unity was great but now I don’t know…
duddes ,ı guess ı’ve solved that .JUST NEVER
RUN AS ADMINISTRATOR. or what the hell was true sentence,ı guess you all understand me already,.Sorry my english not good 
I used the program compatibility troubleshooter. (Right click the file, go to properties, click the compatibility tab) worked for me
Found a fix for me. I had set Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Null\Start to 4. Set it back to 2 and the issue should be fixed
You can use RUN AS ADMINISTRATOR for Unity but along with a HUB. Both, Unity and Hub should be RUN AS ADMINISTRATOR then everything will fine.
Saya ada kendala saat mau buka Unity, saya buka lewat Unity Hub, tapi pas mau buka project dan klik, cuma berputar seperti sedang loading dan tidak muncul apa-apa, bagaimana cara mengatasinya?
