AVD host Entra ID joined only - logon issues.

Hi AaronE430,

I see you're facing a login loop issue with Azure Virtual Desktop (AVD). This problem is not uncommon, and there are several potential solutions based on the information I found:

1. Conditional Access Sign-in Frequency:
   If you've set a sign-in frequency for conditional access, users might encounter issues when their session times out. The error code 70044 and the failure reason "The session has expired or is invalid due to sign-in frequency checks by conditional access" suggest this could be the issue.

2. Client Version:
   Make sure you're using the latest version of the Remote Desktop app. If using the Microsoft Store version, consider uninstalling it and installing the latest version from the Microsoft website.

3. Azure AD User License:
   Check and renew the Azure AD User License.

4. Security Defaults in Azure AD:
   Consider disabling Security Defaults in Azure AD.

Regarding your question about MFA, it's challenging to determine if MFA is causing the problem without more information. If you wish to disable MFA, typically, you would do this through the Azure portal. However, be cautious, as it can impact account security.
