Hi,
I had the same issue. Did you try to launch it with root privilege via sudo ?

Regards.

It runs perfectly on my new Fedora 36 and Ultrafine Display 24MD4KL

Can you run the program through a debugger like gdb ?
# sudo gdb ./LG_ultrafine_brightness

then type "run" and "where" to view the stack at the crashing point.

a "strace" command can be useful to debug it.
# sudo strace ./LG_ultrafine_brightness
