It looks like it is starting at boot but either something is telling it to stop or it is crashing. It may be caused by the file:
/media/80694538-74b9-463c-b35f-1dc951e6bc13/Video/Film/HD/Il collezionista di ossa 1080p (1999).mkv
I would move that file somewhere else so it doesn't scan it and see if everything works.
