Comparing times from the application logs and system logs it appears like the crash happens after a time zone adjustment when the user reconnects.

The system time has changed to ‎2019‎-‎10‎-‎14T18:09:48.853512500Z from ‎2019‎-‎10‎-‎14T18:09:48.853512500Z.

Change Reason: System time adjusted to the new time zone.
Process: '\Device\HarddiskVolume1\Program Files\Citrix\ICAService\PicaShell.exe' (PID 16040).

You could try disabling the clipboard to see if that helps narrow it down. Looks like an error in vclipbd.dll. The time zone error could just be related to the policies kicking in on reconnect and using client time zone policy.
