I would suggest creating a bug report. Your last several posts have just been different stack traces. Nobody on these forums is going to be able to help you give the information you provide.

Aside from a bug report, you could try update unity to its latest 2021.3.x version and see if the issue still persists.
Unless you’re stuck on 2021.3.4 for some reason.
