    Hello

    Thank you for posting in Microsoft Community forum.

    1. Would you please provide the information that the issue occurred on Host disk or Hyper-V disk?
    2. Please try clean boot to exclude third party applications interruptions.
    3. Do you have any screenshot?

    Best Regards

    Zack Lu
