Hi,
Please understand, the dump analysis is not supported from forum side, if the issue is urgent and cannot solved by the solutions we provide, it's recommended to open a business case with Microsoft for further help. They have a higher level and may have more resources to help you.
Regarding your “The computer has rebooted from a bugcheck” question, the 0x3b bugcheck is probably related to system service exception or a network issue.
I take a look at your dump file, and find an error message about SYSTEM_SERVICE_EXCEPTION. The problem may caused by a driver named dxgmms1.sys.
IMAGE_NAME: dxgmms1.sys
I’d suggest trying to disable or update this “dxgmms1.sys” driver and check if this symptom appears again.
