Seems like im having the same issue over here Plex Server running on Raspberry Pi 4 Crashes every morning. Forced to reinstall to get it back up
-- The job identifier is 7633.
Mar 20 08:01:09 raspberrypi Plex Media Server[24127]: /usr/lib/plexmediaserver/Plex Media Server: error while loading shared libraries: libicudataplex.so.67: cannot open shared object file: No such file or directory
On my end per my thread, i use GitHub - mrworf/plexupdate: Plex Update script to simplify the life of Linux Plex Media Server users. and every morning it checks for an update / tries to update. The server then tries to restart but the restart fails due to the missing library, leaving my server down and I need to reinstall to a working version.
Just throwing this all in here incase it helps
