Getting Segmentation Fault

[billyjbryant]

I installed obs-studio on Ubuntu 20.04 via Snapd and I am getting the following error when I attempt to run it:

billy@thor:~$ obs-studio
Qt: Session management error: None of the authentication protocols specified are supported

Segmentation fault (core dumped)

I have attempted to uninstall and re-install. If I run with Sudo it seemingly attempts to run; however, it complains that it can't open X11 and seg-faults as well.

Not sure where to find the dump file to really figure out what is going on, and strace isn't an option because running strace on obs-studio as non-root user errors saying I need to be root.

Please rebuild your font cache and see if that resolves the issue.

sudo fc-cache -f -v

I am encountering this issue also with OBS Studio 25.0.8. Updating the font cache as suggested has not helped, unfortunately.

Adding the "really force" flag (-r) to fc-cache also does not help.
