I have a Windows 2022 Server running on Hyper V Host machine with Windows 2019 and it keeps rebooting randomly. The server is setup as a web server running IIS and was previously running Windows Server 2019 before being upgraded to 2022. I have other web servers that were upgraded to 2022 but they don't have this issue. Event viewer doesn't show much apart from Event: 41 for The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
It is very frustrating, as we don't know why it happens. It happens at random times and causes the websites on the server to go down briefly until it has rebooted. The host servers are Supermicro servers.

Server has the latest BIOS and has had windows updates performed on it. Have to check the list if my server is shown.
Might want to consider standing up a new one, patch fully, migrates roles over to it.
