Did you get any result out of the MS support case? We still face the same issue and also opened a case. Can you share your case number to reference in my support case?
Thank you!

It was corrupt entries within the below registry left behind by Fslogix incorrectly unmounting the UPD. The incorrect registry keys will not contain a ClassGUID, delete them out. In my case I had 4 corrupt entries. Let me know how you get on.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SCSI\Disk&Ven_Msft&Prod_Virtual_Disk

    After deleting those corrupted entries. It seemed to work fine for a while. But a couple of hours later those corrupted entries where back in place and the login issues where back. Does anyone know what we could do to prevent these corrupted entries coming back? We disabled the VHD Compact Disk policy.

      I'm unsure what caused the issue and we haven't experienced it since. We are using v2.9.8884.27471 if that helps. A quick thought, would autoscaling be causing it?

      You'll need to run PsExec /s /i regedit.exe. PsExec can be downloaded from: https://learn.microsoft.com/en-us/sysinternals/downloads/psexec

      I also found disabling this key resolved this on impacted machines once the key was removed: https://learn.microsoft.com/en-us/fslogix/reference-configuration-settings?tabs=profiles#vhdcompactdisk

        Disabling which key resolved the issue. Could you please share the required settings.

         

        Thanks & Best Regards,
