Azure Virtual Desktop - Black Screens on logins - What we've tried so far
Just a heads up, after going through the exact same issue within our AVD Environments we have narrowed the issue down to the Sept 14th Security Update. This patch has cause merry havoc with the AppReadiness Service and how it interacts with FSLogix. I had a 2 hour conversation with MS on Friday concerning this issue, where at first they stated there was no issues with their patch.
For now I have found the easiest solution was to rebuild my environments from a Golden Image Which did not include the September Patch, and manually update to August 2024 Patch then disable the Windows Update service.
After we had done this, we have once again seen stability within our AVD Environment, and have decided to implement a Dev Environment to test all future patches MS Decides to foist on us before rolling it out to general production.
Rebuilding the hosts from a W10 21H2 image from MS, uninstalling any update released after July 2024 and disabling Windows Update to prevent new updates to be installed is exactly what we did on our Windows 10 Multiuser AVD hosts to resolve the issue 100%. Implementing the KIR and changing the registry keys mentioned in https://techcommunity.microsoft.com/t5/azure-virtual-desktop/appreadiness-service-and-black-screen/m-p/1795520/highlight/true#M3241 did not resolve the issue, it only caused the issue to occur less often.
Everything works, including Outlook, OneDrive and Teams (new version) and no more black screens at sign in at all.
