• tried to compare registry from working server Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RDPUDD\Device0
• tried importing TermService from working server
• reinstalling session host feature

nevermind seems to be solved with adding reg key HKEY_CURRENT_USER\Control Panel\Desktop\HungAppTimeout - REG_SZ Value: 30000

Hey Richard. Did you have to add this to every user account? I am facing the same issue, I've tried so many things with no success so far. Thank you.
