I installed Jellyfin via apt last week while setting up my new Ubuntu host, and it streamed several movies and was working great. After a reboot yesterday, it began coredumping with the error above, trying to access a nonexistent /jellyfin path. I've reviewed all my config files and none have a reference to this path. I also ran ls -ld /etc/jellyfin /var/lib/jellyfin /var/cache/jellyfin /usr/share/jellyfin and permissions looked good. I'm not sure what step to take next; I do not know how to inspect the core dump or what to look for.

Thanks in advance for any help you can offer!
