MADE IT WORK!! So I tried this in administrator command prompt:
takeown /F C:\Users\USERNAME\AppData\Local\BraveSoftware\Brave-Browser /R /D Y /A
icacls C:\Users\USERNAME\AppData\Local\BraveSoftware\Brave-Browser /setowner Administrators /T
icacls C:\Users\USERNAME\AppData\Local\BraveSoftware /inheritance:e /T /C
And it worked!! The issue is something corrupted, probably brave is not to blame at all, but windows update or something, but when I went to the appdata and tried to 7zip brave folder (ofc brave was not running) I got tons of “Access denied” errors, which was suspicious and this followed. I’ll fix tomorrow the work browser too
