Thanks for the log files. I do not see anything that would prevent updating Plex Media Server.
Some questions/requests:
Please provide a directory listing, including file sizes, of N:\Plex-Back-up\Plex Media Server\Plex Media Server\Plug-in Support\Databases.
Is N:\ a local or network drive? If local, is it a hard drive or SSD? Is it internal or USB attached?
When you moved the Plex Data Folder from C:\ to N:\, did you follow this procedure, including making the Windows registry changes? [HowTo] An extended guide on how to move the Plex data folder on Windows
