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:

Confirmed problem is not FSLogix. We excluded our local admin from FSLogix to verify.
So far, we have added more Hosts to the Pool due to high CPU usage.
That helped, but we continue to see Users take a long time to login to Hosts.
What I see in Processes is the RDInfra process taking up CPU and "hanging" when I watch my test user login using RDP.
I did follow the troubleshooting tips to uninstall/install the AVD Agents and restart. This did not help.
I have added excluding the folder for the Azure Monitor Agent in AV. I'm testing to see if this helps.
Only one response from Microsoft so far. I was told the team that handles AVD is busy.
Denise Child did you find a solution for this?
I am having a problem with AppxSvc taking up to 10GB of RAM for my AVD hosts.
I am couris because my problem disappear when i disable the service. But then Explorer crash as you mentioned - and also Onedrive etc.
So maybe you found the solution?
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.
