Grey Screen at logon

tony roberts1709152250


We have recently deployed XenApp 1912 LTSR CU1 on windows 2019. We have issues where users have a grey screen at logon and cant get on their sessions. I can see in the event logs we get this error


The Citrix Universal DLL Injection Driver has detected an integrity error during process creation. The Citrix Universal DLL Injection Driver has been disabled.

The Citrix Universal DLL Injection Driver has encountered an unexpected error.


I have seen this article https://support.citrix.com/article/CTX226605?_ga=2.120160842.354598515.1604951328-615832511.1570610895 and I cant see anywhere the reg key mention is interfering with e Ctxhook.


Has anyone else had this issue and did you mange to find out what was causing the Citrix Universal DLL Injection Driver to crash.


Thanks in advance.
