    Hi @Ryan Wilderman ,

    Based on my research, it looks like issue with WMI process on the Windows OS. Please perform a clean boot of the machine and try again. Also, you could try running sfc /scannow and uninstall unwanted software's. Also, try building windows with a new image or ISO if its a new installation.

    Make sure to meet the system requirements
