PCem doesn't open window when starting VM.

[CrypticScience]

I am using Pop! OS 22.04 LTS on Gnome desktop with X11. When I try to start the machine, the main window closes, I get a blip of sound, and then nothing happens. I tried running pcem through gdb, and I get this output:

For help, type "help".
Type "apropos word" to search for commands related to "word"...

(No debugging symbols found in pcem)
(gdb) run
