Azure Virtual Desktop - Black Screens on logins - What we've tried so far
JacobLowe IF people have done the KIR, KB5043064 isn't even visible in Windows update to uninstall. They'll need to re-enable it, KB5043064 becomes visible in windows update, THEN uninstall KB5043064.
Interesting, I could still see KB5043064 listed having done the KIR in Programs & Feature > Installed Updates. Having uninstalled it it seem to have been replaced with KB5041580 in that list however which looks like August's patch Tuesday update which I guess figures. So two hosts absolutely fine, one still look to have the black screen and now AADbroker Outlook/Teams/OneDrive auth issues and one that completely went berserk at 9am and even became completely unresponsive to mouse click in the console session and had a bunch of session stuck in a pending state - yesterday that one was fine (before uninstalling that KB and rebooting!).
I may have jinxed things however by saying to a colleague who came in at 9am that thing were looking ok at that point and we hadn't seen any issues or had any reports of black screens or Outlook issues.
