FSLogix issues with slow login and black screen
FSLogix 2210 hotfix 2 (2.9.8612.60056) Windows (Windows 11 Enterprise multi-session) AVD Hosts What we know: Disable AppXSvc - no slow login, but some apps do not open and Explorer crashes on ...
- We confirmed the problem was not FSLogix by excluding the local admin account from FSLogix. Login times for the local admin was slow too.
What we learned is that AppX was the symptom, not the cause, once we added more Hosts and reduced the number of Users per Host. The login times were back to what we were used to.
We were not able to provide a complete dump to give Microsoft more information for analysis because this is a production environment.
Here are a couple of the ways to help troubleshoot if you are having the same problems with slow logins:

zzdallepNo I have not found the solution to AppXSvc. I see it take 3GB to 4.6GB RAM, but never 10GB of RAM.
We are still monitoring the Hosts for the slow login/black screen. I did send logs over to Microsoft on Friday.
I also noticed that all of our Hosts have an update to the RD Agents 1.0.7539.8300 and a new RD Client version was released to version 1.24583.0, so I am hoping this intermittent problem goes away.
zzdallep I see the huge memory usage for APPX Deployment service now. The other one is the RD Infra Agent that has been causing the slow logins. It is supposed to load and then go away when someone logins, but it "sticks" for a long time, to where I have to put Host in maint mode until is releases.
