Unity crashes approx. every hour with error: Attempt to access invalid address

Hello,

my Unity (Version: 2019.4.22f1) crashes about every hour now. I am getting this error:

ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.' (Address: 00007FF7A7098F0F) 0x00007FF7A7098F0F (Unity) (function-name not available)

Obviously one of the components / packages / assets / whatever is trying to access memory, it is not allowed to. Unfortunately the function name is not available, so I don't know, what is causing this error.

I also cannot send the bug report after the crash, because my project is just too big.

Any ideas how to find it out?

Thank you
Huxi
