Jon, thank you so much for your response! For a brief moment yesterday X-Windows started. This occurred after I set:
Flag = 0 under:
HKLM\SOFTWARE\Citrix\CtxHook\AppInit_Dlls\Multiple Monitor Hook
I then removed:
xorg-server-cygwin-crashreporter
xorg-server-debuginfo
Rebooted and tried again. Alas, back to "Connection refused." I reinstalled those packages but the problem continues. I ran gdb to get a backtrace this morning and we're still seeing the same stack:
#0 0x00007ffa0af83b19 in RaiseException ()
from /cygdrive/c/WINDOWS/System32/KERNELBASE.dll
#1 0x00007ffa0a032086 in ?? ()

#4 0x000000010040df3e in winConfigKeyboard (pDevice=pDevice@entry=0x80027d720)
at ../hw/xwin/winconfig.c:274
I asked one of our developers who has a company laptop (i.e. VPN access, not Citrix) to test his setup. It works. Thus the problem does seem to be Citrix related. I've now reached out to another developer who is running Cygwin 2.11.1. I believe his copy is running while he does use Citrix and Windows 10 1909.
That's all I have for now. The chase continues.
Kind regards,

One of my colleagues discovered the act of change HKLM\SOFTWARE\Citrix\CtxHook\AppInit_Dlls\Multiple Monitor Hook\Flag from 0 to 1 and back again can be a work-around. Immediately after this key is changed X-Windows will start. If one does a reboot X-Windows will fail again. Change Flag and X-Windows works.
Not ideal and we would still like to figure out what is going on, this does get us back in business with X-Windows.
Kind regards,

XWin is just calling GetKeyboardLayoutName() here, which Citrix appears
to be hooking.

This is a crash in Citrix, so I'm afraid the best (and possibly only)
people who can debug this are Citrix...
Just Googling the faulting DLL name did I find [1], which seems to
indicate you can turn off this hooking with a registry key.

Hi Everyone.
Following a Windows 10 version 1909 update Cygwin/X fails to start. It ends with:
