SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff8003470adbb, The address that the exception occurred at
Arg3: ffffbb01cfaea978, Exception Record Address
Arg4: ffffbb01cfaea1c0, Context Record Address

Experience the very same issue lately, BSOD on Windows Server 2016,

• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e),
• at IofCallDriver,
• in volsnap

And this four times in about four weeks.

Some say: Change HKLM\SYSTEM\CurrentControlSet\Services\VSS\Diag from Default to Disabled, and reboot afterwards.

Hope helps. Will have this posting updated, if or if not.

**(Update 04/29/21) Seems so: Did not happen since then. **
