Citrix Workspace 2002 on Mac Pro 2019 (7,1) causes loginwindow/WindowServer crash on Catalina (10.15.4)

[foonon]

I've been experiencing loginwindow/Workspace crashes on my new 2019 Mac Pro (Mac Pro 7,1 3.3GHz 12-core Intel Xeon W, 48GB DDR4 ECC RAM - 10.15.4 - 2TB SSD - AMD Radeon Pro 580X 8GB - 27" LG Ultrafine 5K Display) when I wake the display. This happens reliably when I'm running Citrix Workspace sessions but it also happens seemingly randomly.

The crash report says this, always with the same stack trace on the crashed thread:

The full crash report should be attached.

The result of this error is that I'm booted back to the login prompt and I lose my session.

Anyone seen this before with any other application? Any advice to help me track down and fix the cause? I've already disabled SIP and I've tried it when booting to 'safe mode' with no change in the behavior.

This only happens when I'm running Citrix Workspace 2002 + the HDX Realtime Media Engine 2.9 (latest versions)

I uninstalled the softRAID product that came with the Accelsior 4M2 PCIe M.2 NVMe SSD card

I also uninstalled Winclone 8

Also, I plugged my usb headset into the Mac Pro itself instead of the LG Ultrafine 5K monitor

Additionally, I unplugged the Magic Keyboard from the back of my display, so I'm using it wirelessly now.

It seems that one or more of these things fixed the problem for me. For now, anyway.

I wasn't really expecting any of these things to fix the problem, but it seems that one or more of them did and frankly, this has sucked up enough of my life so I'm not going to go back to try to figure out which one or combination of these changes made the problem go away. Maybe one day, I will.
