Crash on Start For Unity Edtior

Unity Engine
1

Hey, I have no idea what is going on here. Unity crashes whenever I attempt to open it, whether it be creating a new project, opening an old project, or even launching it without unity hub installed. I tried updating my GPU drivers, updating windows, un-installing both the hub and the editor, and everything in between. No matter the combination, Unity fails to launch and crashes within a couple seconds of attempting to open the editor. Here is my crash log, which is identical even with every fix I have tried. Any help would be greatly appreciated, I really don’t want to have to learn Unreal lol.

Can you try deleting “%APPDATA%\Roaming\Unity\rest-certificate.pem” and try to start the editor again?

I have no idea if this suggested solution worked for the original poster of this thread, but I had been having problems for the last 2 days with unity. Every version I tried to launch crashed on startup.

I deleted this file and now it works fine, so… thanks a lot! No idea why this one little file would cause a crash that doesn’t explain why it crashed, but anyway, I thought I’d better verify as at least one person that this solution has worked for.

Thanks again!
