Game keeps freezing

My game keeps freezing on the ps4 in the gallery.  It does it when you are starting a new game, and trying to add a family from the gallery.  It even does it on the main screen by going in to the gallery.  You can look at what is all in your gallery, but you can't delete or, add anyone from the gallery without it freezing all the time.  I tried deleted the game and redownload it, but it didn't fix the problem.
