AVD remote app session is stuck on the blank login screen

Welcome to the Microsoft Q&A Platform and thank you for posting your question!

Based on your description, you are encountering an issue where an Azure Virtual Desktop (AVD) RemoteApp session gets stuck on a blank login screen. This behavior is often related to FSLogix Profile Containers not loading properly or becoming unresponsive during the user sign-in process.

I would like to provide a few troubleshooting steps to help isolate and resolve the issue.

Temporarily Disable FSLogix Profile Containers

This will help determine whether FSLogix is contributing to the issue. Run the following command on the affected session host:

Set-ItemProperty -Path "HKLM:\SOFTWARE\FSLogix\Profiles" -Name "Enabled" -Value 0

Note: This disables FSLogix on the host. You may need to log off any active sessions or reboot the server for the change to take effect.

Then, attempt to launch the RemoteApp again and check if the issue persists. If the session no longer hangs, FSLogix is likely the root cause. To re-enable FSLogix once testing is complete, use the following command:

Set-ItemProperty -Path "HKLM:\SOFTWARE\FSLogix\Profiles" -Name "Enabled" -Value 1

Additional Suggestions

• Ensure the FSLogix profile disk (VHDx) is not stuck in a locked state or still attached to another session host.
• Check FSLogix logs located at: C:\ProgramData\FSLogix\Logs\Profiles Look for any errors or warnings related to profile loading or disk mounting.
• Determine whether the issue affects all users or only specific ones, which can help identify profile-specific issues.

Please let me know the results after testing with FSLogix disabled. I’ll be glad to assist further if needed.

Wishing you a successful resolution and a great day ahead!
