Additional context

To debug a little, I went to the folder of the Pictures share, which was empty, and I created symlinks to every file in the Movies folder. So they are now similar in number of files. The app does not crash on the Pictures share.

I further went to look for any dot files in Movies or something and there was one, deleted it and the same still happened. Not sure why this could be happening.
