I've been using RH 2.1.3 almost every day and previous versions before that on Ubuntu linux (currently 18.04). I was using it last night, but when I went to launch it today, the splash screen outline would come up then go away. I ran it from the console and got an unhandled exception which I'm documenting below. There were two apt updates that happened. One yesterday (but I didn't reboot, so the kernel change would have taken effect today when I started the machine), and one today. Here's the list of what got updated in those 2 updates:

Any idea on what might have happened or how I can get it back working again?
