This is problematic.  Nested folders will definitely lead to a lot of misidentification and scanning issues.  Jellyfin expects all of the movie folders to be at the top level of the folder your library is pointed at.

I don't know what an acceptable solution for you would be.

The best solution, from the perspective of making Jellyfin happy, is to move all of your movie folders out of these year folders directly into the "Film" folder.  Easy to do.  Not easy to undo if decide to go back to this year folder organization.

You could also make separate libraries for each year, but that would clutter the UI and make movies hard to find.

If you are committed to using Jellyfin, you might need to get over having your files organized this way.  At the end of the day, you are using Jellyfin's interface and won't be interacting with the files.  I fought with this myself when I first started using Plex, and now Jellyfin.  But decided to just make Plex/Jellyfin happy and organize and name my files in a way that makes auto-identification more likely.  Since I watch all my media through Jellyfin now.
