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:

Hi,
Remove all Group Policies that are being applied, any printers or mapped drives, these can sometimes hinder logins. If you find it works better, re-apply GPO's one at a time.
With FSLogix enabled, look in the FSLogix event log, any mapping errors? Does the profile store have enough space?
If you disable the FSLogix service and allow it to load local profiles do they load correctly/faster?

*Disabling FSLogix loads faster. I had already confirmed that in the above.
*No errors in the FSLogix logs.
You did give me an idea about GPO's. I already confirmed with no GPO's no change, however, we only exclude VHD & VHDX in AV, so I added the path for the FSLogix folder into the path exclusion and that cut the time to load down by half.
Sandbox is an image of Production where I am doing all of the testing.
Thanks!
