Hello Seth Foley, if possible you could now install gdb and the following debug symbol packages. The latter are stored in a separate repository, more details in [1]:
handbrake-dbgsym libavformat58-dbgsym Then if you have not rebooted since the last handbrake crash, you can use following commands: coredumpctl list coredumpctl gdb <PID> bt quit And forward the output again to this bug. Maybe you want one copy one of the cores in /var/lib/systemd/coredump/ to a safe place, because after some time they get automatically deleted. >From your last output I guess something like in [2] would be produced. Unfortunately I have not found any bugreport in the upstream projects. What I find in the sources it looks like avio_open2 is called with an invalid pointer in filename later, but maybe the maintainer know something more...
