Thanks for the logs
They show you have crash reporting disabled
Jun 07, 2021 18:30:26.567 [9948] WARN - Crash: Crash reporting disabled
Could you look into these directories for any files and if you find any recent ones, zip and send to me indicating which directory path the files were in
Look into recent / current Plex Media Server versions directories below
C:\Users\GreigFamily\AppData\Local\Plex Media Server\\Crash Reports directory
eg
C:\Users\GreigFamily\AppData\Local\Plex Media Server\\Crash Reports\1.23.2.4656-85f0adf5b\PLEX MEDIA SERVER
The logs you provided show there was a crash at Jun 07, 2021 04:52:51
I can see similarities in the log to those from user crashes i investigated here Long Time Plex User - First Major Issue that I cannot resolve
Would like to see zip of the Plex Media Server database as well
C:\Users\GreigFamily\AppData\Local\Plex Media Server\Plug-in Support\Databases\com.plexapp.plugins.library.blobs.db
C:\Users\GreigFamily\AppData\Local\Plex Media Server\Plug-in Support\Databases\com.plexapp.plugins.library.blobs.db-wal
C:\Users\GreigFamily\AppData\Local\Plex Media Server\Plug-in Support\Databases\com.plexapp.plugins.library.blobs.db-shm
Also database files with filenames starting with tv.plex.providers.epg.
Thank you
