AppReadiness Service and Black Screen
StevenR , The server is all patched, has the registry keys added and the latest FSLogix version installed too, it was fine until yesterday when this started again with no changes applied and rebooting cleared it for about 5 active hours. I only have the one VM to keep the costs down but I'm going to go with having two and shutting down one at a time in future. With only 5 or 6 users active at a time it never strains and works well, except for this particular issue. I am looking to build a new pool from scratch on 20H2 to ensure nothing came through the original image. I'll report back once that's built.
Thanks

Has anybody resolved this yet? It's March 4th, 2021.
We have a case open with Microsoft but after two weeks we're no closer to a solution.
Windows EVD 20H2 19042.804 (fully patched)
FSLogix 2.9.7654.46150
Black screen for 30-90 seconds at logon.
Registry keys from here do not help, and some logons end up with a broken start menu and inability to authenticate to Office365

Hi aaronmountford ,
Sorry to here that, if its happening every time it might be worth building another VM to add to the mix put it on win 10 2004 and use GPO/computer/policy/administrative/windows updates/(something) for business and set it to hold the version at 2004 while MS resolve the one that doesn't work, I am running the same versions as yourself and I am not seeing this issue. also how many users do you have on what size VM?
Thanks StevenR
We actually have 4 in a pool (well currently 3 as one is out for troubleshooting). Two are built from an image mid last year (20h1-evd-o365pp), and two from an image from late last year (20h2-evd). Both receive updates as per our security policy. The sizes are all Standard D4s v3.
We don't have a heavy load on them, peak usage on each would probably be 15-20 users but that's a guess. Could be less. Even with just 1 user we get this issue, so it's definitely not performance based.
The one thing we have determined is that disabling the FSLogix services removes the issue completely, although it introduces a bigger problem - group policy fails to apply if the FSLogix services are disabled.
For what it's worth we're using FSLogix with cloud-cache only (Azure Files).
aaronmountford 15-20 users per VM!! on a D4 what are they doing on there (outlook/teams/web etc)? as recommendation is 2 per cop so D4 = 8, i have found realistically 7 on a D4 is more accurate and comfortable.
I cant image putting 15 on a single D4.
