Could not create PlexData share

The PlexData creation error is not fatal to PMS starting.
In PMS 1.20.2, PlexData will no longer show any errors. Its usage will be completely optional (works if present - ignored if not present)

As for PMS not starting, may I please see the entire ZIP set?

Go into PlexData,
Click “Plex Media Server”
Right-Click “Logs” -> Compress (generates a ZIP file)
Upload the composite ZIP here.
