Intermittent Blackscreen issues with FSLogix

We've been having intermittent issues with Blackscreens with some of our customers whether its on AVD or Local Terminal Servers.

We were able to partially track it down to the App Readiness Service and followed instructions from an article about AVD and FSLogix.

After applying the reg keys from the article we were able to fix the issue for some but it seems that even still this randomly happens but less than before now. 

Is there anything to look out for with new environments in terms of settings or hardware specifications to prevent this fully? 
We are almost at the point to just migrate to local profiles with customers that are having this issue, which I am trying to prevent us doing.

 

Does anyone have similar issues or an idea on the right way to fix it fully? 

I am happy to provide additional information if it can help. 

 

Reg Keys: 

HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\ExplorerAppReadinessPreShellTimeoutMs7530 (DWORD)
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\SystemFirstLogonTimeout30 (DWORD)
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\SystemDelayedDesktopSwitchTimeout30 (DWORD)
HKLM:\SOFTWARE\FSLogix\AppsCleanupInvalidSessions1 (DWORD)
