Azure Virtual Desktop - Black Screens on logins - What we've tried so far
It seems that adding more AVD session hosts has stabilized the situation in our case.
It seems that the “appx stack” starts crashing when the stack is under load/stress. This happens during logon storm (users logging on at the same time in the morning) and also when the host has more than +/- 10 users working on it.
To mitigate this, we make sure we have plenty of AVD session hosts so all of them are online during the logon storm + we make sure that a AVD session host has max. 10 users connected to it.
We also applied the KIR (https://download.microsoft.com/download/a7ee9dc7-dfc9-498d-808c-86f2c046a55d/Windows%2010 20H2, 21H1, 21H2 and 22H2 KB5040525 241001_01051 Known Issue Rollback.msi) in the master image and redeployed all our AVD session hosts from that new master image version.
Hopefully MSFT comes up with the fix soon so we can go back to the previous situation as this mitigation has some impact on the costs.
seems to be solved in the cumulative update for November. Preview can already be installed since 22/10/24, see https://support.microsoft.com/en-us/topic/october-22-2024-kb5045594-os-build-19045-5073-preview-f307a4b0-f62d-4c28-9062-44207aea55c3

the svchost.exe_appxsvc is not crashing anymore - but!
this entry is still in eventviewer:
Failure to load the application settings for package Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy. Error Code: -2147024893
Meaning Teams/outlook/onedrive not doing so wellHaving same event 'Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy.'
Running the following in powershell, it returns status OK
Get-AppxPackage -Name "Microsoft.AAD.BrokerPlugin"
I've also gotten the first black screen out of 50 logins, it did eventually log in but the start button is non responsive- I'm still getting that too
Repair for operation LocalSettings against package Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy with error -2147009096 returned Error Code: 0 - I am pretty certain someone spoke about a fix for this in this thread. When appx went haywire your appx corrupted some of the installs. I am fairly certain it's in this thread that someone discussed a fix.
