Googling only finds me this old thread:

Hyper-V VM Snapshot Issue

hi One of my windows 2016 hyper-v vms is not able to create the snapshot for the backup using the latest hyper-v client. When I run the urbackup hyperv_snapshot.ps1 powershell script from powershell cmd I get this output ProcessWMIJob : Exception of type 'Microsoft.PowerShell.Commands.WriteErrorException' was thrown. At C:\Program Files\UrBackup\hyperv_snapshot.ps1:151 char:13 + ($job | ProcessWMIJob -WmiClass $Msvm_VirtualSystemSnapshotServic ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~…

In this case I think the issue is VSS issues within the VM. Perhaps try to create a production snapshot from the UI to confirm it cannot create production snapshots. Then look at the event log within the VM.
