We have noticed problems with the start menu on some Windows 11 installations. This does not open when the left mouse button is clicked. Instead, the following event is logged in the event log at the time of the click:

We analyze StartMenuExperienceHost.exe with process monitor and see that it loads the following Citrix DLL: C:\Program Files\Citrix\HDX\bin\Citrix.Hooking.Uwp.Bridge.dll
This is confirmed by the observation that the problem occurs after installation/update of Citrix VDA.
In Citrix, a deactivation can be carried out with ExcludedImageNames by CtxHook. The following command takes effect immediately - without a restart:
reg add HKLM\SOFTWARE\Citrix\CtxHook /f /v ExcludedImageNames /d StartMenuExperienceHost.exe
Maybe the same problem can also occur with other applications that injecting themselves to StartMenuExperienceHost.exe.
