I installed Gaupol to do some subtitle editing and tried to start it. It immediately crashes the desktop and sends me to the login screen. This is completely repeatable and reliable.
Is there a way to record logs of some sort to see what is causing it to do this so I can hopefully fix it and go back to using the program?
I'd try to launch the application in terminal and redirect output to file like this:
$ app_name > log.txt
or
$ script log.txt
$ app_name
plus investigate logs in /var/log
Thanks! I ran the second one and got this:

Any idea what is causing my issues?
Alas, I see only warnings which can not nuke desktop session.
Deeper debugging may be logging application system/library calls using strace or ltrace commands. See man for these commands for more details.
I think I'm going to try a live environment install and if that doesn't give issues try a fresh install. Thanks.
Doing a fresh install fixed it.
Did you try looking at your system logs, e.g. journalctl -r? This will usually include information about what triggered the logout/end-of-session.
I say this in almost every other thread now, but a handy way to test stuff out is with virt-manager. That way, you can keep using your desktop while you experiment with a fresh image.
