So I cannot be 100% sure as I’m a linux guy and windows is completely alien to me. However …

Jul 10, 2026 13:15:04.172 [436] DEBUG - Scanner: Processing directory F:\Music\Vitruvia\Broken World (parent: yes)
Jul 10, 2026 13:15:04.172 [436] WARN - Error scanning directory, we'll skip and continue: boost::filesystem::last_write_time: The system cannot find the path specified [system:3]: "F:\Music\Vitruvia\Broken World"
… this error scanning along with other errors related to F:\Music\Vitruvia in your logs could mean plex cannot read the files correctly and its tags and then its failing back to their cloud matching, Vitruvian vrs Vitruvia. I’d suggest fixing that error scanning and then try the plex dance again and see if it helps.
Otherwise lets see if someone else from plex or the community has any idea based on your logs.
