We're experiencing a frustrating issue where users are trying to log into our Azure Virtual Desktop (AVD) environment. After entering their password and clicking "OK," the authentication dialog freezes for 5-8 minutes before finally logging them in. Sometimes, rebooting the system seems to fix the problem temporarily, but it usually returns by the next morning. We've tried troubleshooting by checking for Kerberos cache issues and clearing out the Credential Manager, but the web access works fine—it's just the Windows App that's causing problems. Has anyone else faced this issue?

It sounds like you might be dealing with a problem introduced by the recent Windows update KB5074109. Many users have reported that this update is causing authentication failures with the AVD. When they try to connect, it gives an immediate authentication error. It's affecting multiple devices and seems to be a widespread issue rather than something specific to your setup. Uninstalling that update might help restore functionality until a fix is provided.
You might want to check the latest release health updates from Microsoft regarding Windows 11. There could be ongoing issues related to the latest builds that affect the AVD login process. Just keep an eye on those updates for any announcements regarding fixes or patches that could potentially resolve your situation.
I appreciate the tip! I’ll monitor those updates closely.

Thanks for the info! We’ve been struggling with this for a month. Hopefully, uninstalling that update will help us!
