Unable to connect to Azure Remote Deskop after updates

I have some additional information to report about this issue. I have found that users who are a member of Domain Admins in the AD DS domain are getting stuck in a login loop when trying to launch apps (including the desktop.) I don't know what would be causing this, but I just got the Microsoft ticket reopened so I can try to understand why this would be happening. The Remote Desktop client populates correctly, but when launching an app, the client shows Initiating remote session, configuring remote session, then securing remote connection, and that's when an AAD authentication prompt opens up. After entering valid credentials, including MFA, the Initiating remote session and securing remote session messages show up again, and then the user is returned to the AAD auth prompt.
