    Thank you for your question and reaching out. I can understand you are having issues related to Bitlocker.

    Bitlocker drive cannot be read on Windows 10 because of difference in encryption algorithm.

    I would suggest you to please turn off Bitlocker then reboot your Server and PC ,

    Then try to Turn On and Encrypt BitLocker again

    May I ask whether you encrypted the OS drive or the data drive?

    If it is an OS drive, you need the recovery key to unlock it; if it is a data drive, you only need to use the password or smart card to unlock it in the control panel.

    Or you can try to hang the VHDX to a computer of the same version to unlock it.

    Or you can try to suspend BitLocker-protection and uninstall the new patch.

    Hope that helps you.

    Best Regards,
