Running into a couple issues updating stuff. How do I confirm the permissions JF has on Windows for folder access? Most the stuff I see that pops up on Google is for Linux/Docker etc.
In task manager details, check what user is running jellyfin. Then right click on the folder with your library, properties, security tab, with your library and make sure that user owns the folder.
Jellyfin 10.9.11
Ubuntu 24.04 LTS (bare metal)
Intel i3 12100 on Asus Prime H610M-E D4 mATX
32GB DDR4-3600
Intel Arc A380
OS drive - SK Hynix P41 1TB
Storage

WD Red 3TB CMR (WIP Media, Test libraries)
3x WD Red Pro 6TB CMR in RAIDZ1 (JF Library)
