New movies not added to library anymore and metadata fetch no longer working

[TheDreadPirate]

According to the last log you shared your library is pointed at /data/movies. And not each of the letter sub-folders inside it.

And it looks like within each letter folder, most of the movies are not in their own folder.

You need to, either, add each letter as a library root instead of /data/movies (you would need to remove this folder before adding each letter) or move all the files up to /data/movies and, preferrably but not required, put each movie in their own folder.
