Plex won't start on iMac

Server Version#: Unknown as I can’t run it. I installed the latest update yesterday morning.
Player Version#:

I have been running plex on my 2013 iMac (OS Catalina 10.15.17) for several years, suddenly it won’t open. I was in the middle of creating a music playlist of about 500 songs when it crashed and I haven’t been able to reopen it. I have attached the log files.

Any assistance gratefully received.

From the Plex Media Server.log:

You can attempt repairing the corruption
https://support.plex.tv/articles/repair-a-corrupted-database/

If that doesn’t work you can try to restore from a database backup (if you have configured your server to automatically create such backups)
https://support.plex.tv/articles/202485658-restore-a-database-backed-up-via-scheduled-tasks/

If you have no such backup or restoring the backup fails, your final option will be to nuke that server and to start over.

Tom80H, thanks very much. I took the coward’s way out and deleted the database. Server didn’t start initially, even after a reboot. Got it going indirectly, through Drop down menu. Now rebuilding database which will presumably take hours if not days. Thanks again.
