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:

- In addition, we have a proprietary app that we have not updated in a few years, but is in Test, which could be the cause of the high AppX memory usage. We plan to verify on one Host to see if this helps and maybe we can go back to the lower number of Hosts with higher number of Users. We only use AVD for two apps and OneDrive. I'll update this post once we confirm.
- The problem was we made a lot of changes to the FSLogix Profile settings when we changed to Win11 Image for the Hosts and upgraded to the latest FSLogix version. Once we deleted all of the Profile Folders for the Users all issues were resolved.
