Yes indeed its a fault in a MS service - the question is which one?

Code:
amsi.dll!ATL::CComObject<class CAmsiAntimalware> vector deleting destructor'(unsigned int)

Starting in Windows 10, version 1903, if your AMSI provider DLL is not Authenticode-signed, then it may not be loaded (depending on how the host machine is configured). For full details, see IAntimalwareProvider interface.

Your antimalware possibly created the issue.
You should open a new post with appropriate logs and alert @zbook

So no crash? Just an event log exception?
This could have happened because of a process restart triggered by WU as mentioned in the log.
Stay away from the event logs, you'll sleep better. :LOL:

No, a definite exception but it's being caught by the Just in Time debugger.
