Answer

Hi,
The LM_SERVER_INTERNAL_ERROR bug check has a value of 0x00000054.

This bug check appears very infrequently. The website doesn't give particularly effective information.

https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x54--lm-server-internal-error

For the dump information, it seems to be related to smb and srv.sys. I find the system version was updated in 2020.8. So please check for update, install the latest security updates to update the files version and fix smb.
Hope this helps and please help to accept as Answer if the response is useful.
Best Regards,
Carl
