Edit. Seemed to be solved/working now.

Not sure if this is the right place but I'll post it over at r/plex as well I guess.

I've been running Plex for music for years without issues. Suddenly, any new albums I add show no album art — just the artist poster or blank. Old albums are fine.

Settings:

• Prefer local metadata: On
• Album Art: Local Files Only (also tried Local & Plex)
• Using embedded art + cover.jpg/folder.jpg

What I've tried:

• Full server restarts
• Refresh Metadata / Analyze / Scan Library Files
• Clean Bundles + Optimize Database
• Fixed permissions recursively on Music folder
• Removed/re-added albums (including previously working ones)
• Tested in a brand new Music library (works perfectly there)
• No hidden files, manual cover.jpg works if I edit the album manually

The main library's scanner just isn't picking up
local art on new content anymore. Logs show UltraBlurProcessor decode failures, metadata matching issues, and "unknown metadata type: folder".

Plex 1.43.2.10687 on latest macOS, library on external volume (~3TB music).

Anyone seen this before or have ideas beyond what I've tried? Thanks!
