Keeps Crashing

I love this game so much, but ever since I got to the "Spilling the Beans" mission the app keeps crashing. During the mission when I get to the top of the boat and try going into the room it freezes. Then I try doing another mission and the app crashes. Ive tried everything and I cant get it to work. It would help if you had an update.
