Solved! Coredump while trying to open on Debian 12 AMD-64

Never ran sdrpp, so new install... Trying to run I see a window open and close very quickly. tail syslog shows:

I'm not sure how to interpret this. Apparently, something choking in libX11? Any help is appreciated. GPU is builtin.
VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
glx gears runs, so I believe opengl is working fine.

If I use Guacamole (RDP over HTML5 gateway), essentially doing a remote login, it works fine. The line that followed the "ConfigManager locked, waiting..." above is "Using OpenGL 3.0". Apparently, something using OpenGL 3.0 works via RDP, but not directly.

FOUND THE ANSWER ON MY OWN!!! Yeah! I kept Googling and when I used the term "libAppProtection.so" that was showing up in the dump, I found this! https://www.reddit.com/r/Citrix/comments/153mcy3/citrix_app_protection_breaks_wordperfect_for_linux/?rdt=54993 . It appears the libAppProtection has something to do with Citrix Workspace (an app I use for remote access). I remove the Citrix software and BAM! Thanks for a great app!
