"ManagementException: Invalid class" while creating/deleting images or clones

This exception may indicate that the affected machine's WMI repository is corrupted. This is a data store maintained by Windows.

Depending on the exact cause, a diagnostic step is to open a PowerShell window and run:

  1. Get-Disk
  2. Get-Command -ParameterType MSFT_DiskImage

If either command results in an error, it may be necessary to restore functionality by repairing the WMI repository.

  1. net stop winmgmt /y
  2. Winmgmt /salvagerepository %windir%\System32\wbem
  3. Winmgmt /resetrepository %windir%\System32\wbem
  4. net start winmgmt

You will need to restart the affected machine after running these commands.
