I have the same problem, and I'm on: 98.0.4759.15 and Windows 10

@leocg I disabled extensions in my browser too (I don't have much of them anyway), but it does not work.
What do you mean with the "broken profile"?
It happened right after last update. It was working fine, and after update/restart it does not work anymore...
