Azure Virtual Desktop - Black Screens on logins - What we've tried so far
Hello, so here's our experience with the issue.
The CU seems to have fixed the root cause issue of black screen/app readiness/AppxSVC, but did not repair or rollback any of the corruption that has been done. In other words, the issue could still persist on a per-user basis depending on which host it would connect because of the resulting corruptions.
We had a chicken and eggs sort of issue where the user AADBroker Plugin was corrupted and some hosts weren't able to redeploy the AADBroker Plugin which would then recreate the black screen issue.
We tried to repair the integrity of the hosts, we tried to reinstall all APPX packages.
We haven't found anything that could make an unstable host stable again.
The funny part is that if a user that has corruption have his profile clean and reconnect to a host which can redeploy the AADBroker, then the issue was resolved, but it was a pain to define which hosts were corrupted and which weren't.
Because we didn't want any lingering issues or corruption, we redeployed a new image, which has all the patches, and we're hoping in doesn't come back. With the new image, we can repair the user AADBroker if it persists too.
Hope this is clear.
And btw, we have a case with Microsoft and we haven't received a single solution attempt.
- It's a shame it has left corrupted appx/msix installs. I see it with our uninstaller also. It has to be a little more forceful to uninstall Ms store apps with Appx commands now.
AdamMc I only found this thread today which has been very helpful.
I've had to install KB5045594 manually from the update catalog https://www.catalog.update.microsoft.com/Search.aspx?q=KB5045594 , I couldn't get it to appear in Windows Update 'Optional Update'.
For anyone else going do this path, thought I'd mention when you install the KB it looks like it hangs. Progress bar goes to about 1/4 of the way and sits there for ages. Stick with it, after maybe 15-25mins it jumps to complete and prompts a restart.
Found out the hard way on the first host when I thought it hung up, cancelled out and rebooted. Luckily it recovered itself at start up (another 35mins).
So far so good on the patched hosts, no further errors or black screen.
4 hosts done, 10 to go!
F-U very much Microsoft! 😉
- Was this on Windows 11 multi session hosts you installed the update?
- Last week, Microsoft Engineers requested us to remove the October and September 2024 patches. Initially, this resolved the Black Screen and APPX Crashes for a day, but the issues reappeared the following day. We installed the new KB5045594 update on Tuesday night. While there were no reported issues on Wednesday, the same problems have resurfaced today (Thursday). Is anyone else experiencing these issues with the new Preview KB5045594?
