That was the mistake - which I detailed here:
Since you still have all your metadata in the Plex
shared folder, you are correct to
Uninstall + ERASE
You may need to do this twice – but be careful not to do too many time else you’ll erase your actual data.
You will know all is well again when:
- All your metadata has been removed from the Plex shared folder.
- The new “PlexMediaServer” shared folder has “AppData/Plex Media Server”
–and– - Your server is again operating normally.
EDIT: Apologies for the double-post with Trumpy.
