Bug Editor 2020.3.32 : Terminating app due to uncaught exception 'NSInvalidArgumentException'

I updated from 2020.3.29 to 2020.3.32 and I'm getting this crash VERY often, usually when I save changes in scene or compile.

Before the update I didnt have any problem, actually Unity didn't crash for months.

I'm using MacOS BigSur and building for iOS

Okay now I open the project again and just by pressing cmd+s the editor crashes the same way.
Any hint of why this is happening?
