Yeah copy-and-past the code from your game.
In case it's a black screen freeze up, then such behaviour is most common for trying to change player character's room to the current (same) one in the "before fade-in" event -- then you may effectively get an infinite loop:
room changes, before fade-in runs, room changes, before fade-in runs, room changes, etc...
