Azure Virtual Desktop - Black Screens on logins - What we've tried so far

TLDR - Azure Virtual Desktop Black Screens.  Could be 2 Min long, could be much longer.  Tried removing stuck profiles, spun up all new VMs to see if that would fix it, finally disabled an applicatio...

Do you know if there is a similar KIR for Win11 hosts? Dealing with the exact same thing.

Look likes Microsoft should fix it soon :

Microsoft has identified a bug affecting Azure Virtual Desktop. Users are now experiencing intermittent black screens for 30 seconds to 3 minutes during sign-in.

This issue is linked to the patch update KB5043064 (OS Builds 19044.4894 and 19045.4894), installed on September 10, 2024

After reviewing application logs, we found that the AppXSvc service is crashing due to an uninitialized m_targetUserSidString in the OSIntegrationManagerHost::Initialize. (event ID 1000)

Per Microsoft, a permanent fix is pending and is most likely to be fixed with October patch.

Here are some workarounds suggested by Microsoft :
Uninstall the problematic updates: Go to Settings → Windows Update → Update History → Uninstall Updates. Select KB5043064 then click on Uninstall and reboot your system.

    jlou65535 it's Funny that he suggest it's just Azure Virtual Desktops. Check the logs on any win10 device with Sept Cumulative update and it has the same errors. Them attempt to do any Appx related commands and find yourself Facing RPC Errors. I uninstalled Sept Cumulative update as a test and it cleared up the app crashed in event viewer and restored Appx. I also tried installing Oct CU and the fix is not included yet.

      AdamMcCorrect, I saw this one related to just that: https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/remove-appxpackage-allusers-causes-application/221b3122-56be-4140-9764-6765cf461e4d?messageId=9079a819-9046-4cf7-be60-c855e0b39d48&page=1

        • henrikmc2 Do you happen to know what exactly that KIR rollback changes? This situation is frustrating. I see someone posted the KIR and by the looks of the KB in the picture its related to a previous month Cumulative update preview.
