AppReadiness Service and Black Screen
We have solved the problem.
It was a latency caused by the loading of the windows app base at each user connection.
Indeed, this database is loaded and read for each connection and its size increases which slows down the connection process (event viewer\Applications and Services Logs\Microsoft\Windows\AppReadiness\Admin)
You must therefore stop the service, delete the files located under %ProgramData%\Microsoft\Windows\AppRepository\StateRepository* and restart the service.
Be careful because the modification of the key of register will handicap the operation of the service and can in the long run make disfonctionnement largely Windows, the office suite, the maj Windows and cause problems to the user profiles.

We have tried this, but for us this didn't help. We are using Windows 2019 with RD-Broker and RDSH servers and FsLogix. When writing this, we tried https://msendpointmgr.com/2021/06/17/fslogix-slow-sign-in-fix/ and this worked for us for a second, we only deleted the Notifications key, then it worked fast, when we created the key again it was slow again. So really strange, we stil haven't found a well working solution. We are now between 30-60 seconds logon time.
