Window 10 - after joining domain administrator account cannot logon via RDP

Question

Hello,
we are creating our new Active Directory Domain (DC are Windows Server 2016 and domain functional level is 2016).
We're trying to join a W10 20H2 VM to this domain.
Before joining domain we could log on this VM via RDP using Local Admin Account.
After joining domain we can log on this VM via RDP using standard Domain User but not using Domain Admin accounts or Domain User that are member of the local Administrators group of the VM.

In event viewer we can find these events
Event ID: 21 Remote Desktop Services: Session logon succeeded

Event ID: 22 Remote Desktop Services: Shell start notification received

Event ID: 40 Session <X> has been disconnected, reason code 1

Reason 1 means that the disconnection was initiated by an administrative tool on the server in another session, so i move the computer object in another OU where Block Inheritance setting is enabled, but this not solve the issue.

With Server OS (like Windows Server 2016) we don't have this issue.

Any Idea?

Thanks

UPDATE_20210412: this issue occurs only on Windows 10 20H2 Virtual Machine. I tried a Windows 10 20H2 installed on a physical PC and everything works fine.
Are there any issue related to VMWare Windows 10 VM?
