Windows 10: Win 11 Pro - Hyper-V system fatal crash w no BSOD

Hi,Any help here would be tremendously appreciated. Just had my system literally power off all of a sudden as I was writing an email in gmail and lost everything I was working on.

How Do You Start The Hyper-V Manager After Installing Hyper-V On Windows 11 Pro?

I have a Dell XPS 8930 running Windows 11 Pro. Virtualization is enabled in the BIOS. I installed Hyper-V using Programs and Features, rebooted, and the Hyper-V services have a Startup Type of Manual (Trigger Mode). However, when I search for "Hyper-V Manager," no application is found. I know the Hyper-V manager is managed through an MMC snap-in, but I don't see a relevant snap-in to add. Also, Hyper-V Manager is not listed under Windows Tools.
