MacOS(BigSur) builds crash on startup. Editor crash when opening projects (ver. 18.3.0f2)

Unity Engine

I made my first few mini-games(3D) last year in June (it was on Mac Catalina) and the builds were working perfectly fine.

I didn’t touch them for the rest of the year and I updated my Mac system to Big Sur a few months ago. Today, I wanted to open the builds up again but it all crashed on startup(I could only see the “made with unity” animation and a few second of my game music).

I also tried to open the project folders, they also crashed when the editor(ver. 18.3.0f2) opening the project up.
Also interestingly, my desktop screen turns black whenever I launch unity.

I am wondering if this is all because of the Big Sur update? – Has anyone experienced this issue on MacBigSur? Most importantly, how do I get my builds and projects fixed? Any advice appreciated, thank you so much!

I also Updated Big Sur yesterday, today unity could not do math correctly… I tried to update to latest version of unity, didn’t work… Then I tried to Download any other version of Unity other than the 2019 3.9 version I have now, I tried 3 and all of them failed? Your not the only one something is going on with Big Sur

This is just a shot in the dark, but could you try opening Unity editor again with “-force-glcore” argument? And then also with “-force-metal”?

EDIT: Hub also allows setting arguments for each project.

currently have the same issue here Big Sur 11.3 Beta (20E5172i). build crashes on launch (previously ok) development build runs ok

The only thing I can think from my build is I request cam,mic upfront on dev build I see the request modal(s).

same here, just swapped to a new MacBook Pro with Big Sur, and any project I try to open crashes Unity Editor. Deleting Library project folder beforehand only results in reimports, then same crash. any clue what causes this?
