Azure Virtual Desktop authentication loop

Using the GA client does not solve the problem. There is no error in the Event Viewer on the client. I can only log on with the local admin account. To do so, I need to disable Azure AD SSO.

I notice that an Event ID 4625 is logged in the Security event log of the VM every time I try to connect with an Azure AD account. The Failure Information of the event are:
Failure reason: An Error occured during Logon
Status: 0xC000006D
Sub Status: 0xC0000250

I have not found any useful information regarding the SubStatus. (https://learn.microsoft.com/en-us/windows/security/threat-protection/auditing/event-4625)

I am unable to log on with an Azure AD account even when SSO is disabled. I tried these different ways to enter the username, and none are working:
- email address removed for privacy reasons
- AzureAD\email address removed for privacy reasons
- tenant.onmicrosoft.com\email address removed for privacy reasons
- tenant.onmicrosoft.com\email address removed for privacy reasons

I know the VM is Azure AD joined as there is a device object in AzureAD that has the name of the SessionHost. There is a "Client Authentication" certificate issued by "MS-Organization-Access" which is issued to the GUID corresponding to the Device ID of the VM's device object in Azure AD.

The user is a member of the "Remote Desktop Users" local group in the VM.

As you have suggested, I'll contact Microsoft to try to solve this issue.

Thanks for your time MathieuVandenHautte
