Quidd is good but now a problem

This app is amazing and me and my sister was trading stuff I completed all of cypherdens set but I have a problem now and that it crashes all the time before I even get into the app and now I can’t complete my baby blue chica for shadow Freddy trade and I am on iPhone 6s
