I'm getting constant crashes in Unity 6 when either recompiling scripts or entering play mode. It will reload once, maybe twice, without crashing but then crashes consistently the next time Unity Editor recompiles or enters play mode.

I have tried with previous versions of Unity and several different projects and all crash the same.

Relevant part from log file:
