Bug Unity 2020.3.18 Editor crashes on entering play mode

Hi,

I had this problem with the same project on unity 2019.3 lts, but since I upgraded to unity 2020.3.18 it has gotten so much worse, a crash on every 5 or 6 tries to start a play mode.

I will post the information from Editor.log file, please if you have any suggestions I will be very thankful!

I also have this issue. I have to constantly restart the editor because of it. Happens on nearly every 2020 version I try.

 

I'm still getting it and have found no solutions online, when I try to report the error the crash handler... crashes, so I can't even report it properly.
