If you shutdown a VM and you cannot restart it again this might be caused by Read Only Domain Controller (RODC).
If you may seen an error message that a VM cannot start with error code 0x80070569 check if the site the VM is running on has an RODC only. If this is the case you may missed to add the new VM to the "Allowed RODC Password Replication Group" of this site. The error 0x80070569 point to a Logon Failure per https://learn.microsoft.com/en-us/troubleshoot/windows-server/virtualization/starting-or-live-migrating-hyper-v-vms-fails.
Search on the Hyper-V host for System Eventlog for ID 5723 and you may see the VM machine name is not trusted by the local RODC server. Also search Hyper-V-VMMS > Admin eventlogs for event ID 15500 to find error code 0x80070569.
Now add the VM machine name into your "Allowed RODC Password Replication Group" and reboot the RODC and VM. When it comes up again the machine account will be cached locally on RODC and you can start/stop the virtual machine successfully.
