Win10 System Encryption - Pretest Fail - HyperV Guest

[Griffo]

Hi, I know there's plenty of topics on this issue, but i've not been able to solve the issue yet by following any of the suggestions.
I have tried 1.23 Hotfix 2 and 1.24 Beta5.
I'm trying to enable full system encryption for a Win10 guest running inside a 2019 Hyper-V server.

After the reboot, the system DOES ask me to type in the password before booting. The boot order in Hyper-V Manager for the VM shows that the DcsBoot.efi file is the primary boot device.

Secure-boot is disabled.
Are there any more detailed logs that can help me determine why the pretest is failing?

Anyone got any suggestions on troubleshooting this further? I'd still like to try to get this to work.

Thanks

Same issue here.
With host Windows 10 pro and Guest Windows 10 pro. Everything works.
With host Windows 10 pro and guest Windows Server 2019, pretest fail.
With host Windows Server 2019 and guest Windows 10 pro. pretest fail.
With host and guest for Windows Server 2019 pretest fail.

Maybe a specific issue with Server 2019.
