Error running headless on Ubuntu server

I’m trying to run gSender Edge on an rPi 4 with Raspbian OS and I’m getting this error on startup. I see the splash screen, but after some time gSender exits. Is this possibly something that’s wrong with the installer, or maybe it isn’t compatible with my OS? Not sure what to do from here. Has anyone else ran into this issue?

jim@raspberrypi:/opt/gSender $ exec ./gsender
