after making a recording and then closing the program OBS will often fail to restart, with the end of the terminal output being a seg fault. This is fixable by deleting the scenes folder (or its contents) and restarting.

How did you build obs? A stack trace with GDB may help to track down what may be causing the crash. Maybe there are other logs too in OBS that i'm not aware of?

apt-get install obs-studio obs-studio-dev

Version reports as 0.0.1 in program, it is really versioned as Debian obs-studio (21.0.2+dfsg1-1) unstable;

Next time it fails I'll use gdb and post that if it helps
