You’ve database corruption. It is bad enough that Plex Media Server refuses to run.
Option: Plex DBRepair Utility
If you are familiar with the Linux CLI, use the Plex DBRepair Utility [Download].
Run it as root. Use the AUTOMATIC option. If it runs into problems importing the database, try the IGNORE option.
If the repair fails, try the REPLACE option, to restore a backup copy of the database.
Option: Restore from backup with FileStation.
If you are not comfortable with the Linux CLI, you can try to restore from a backup using Synology File Station.
Note that this procedure does not check for database corruption, so it is possible that the backup may also be corrupt.
See FAQ 30 - DSM 7 - Database Repair using a Backup copy.
Option: Delete and start over
If the database cannot be repaired and no viable backup exists, then you can delete the database.
You will have to re-create all libraries and reshare them with any friends/family.
To delete the databases:
- Ensure Plex Media Server is stopped.
- Using File Station, navigate to the database folder, /PlexMediaServer/AppData/Plex Media Server/Plug-In Support/Databases.
- Delete everything in the folder.
- Start Plex Media Server.
