To much crashing

So my game always crashes! One time me and someone were fighting in a legendary raid for Moltres and it crashed at the end taking our raid pass and not letting us fight it again! FIX THIS! Oh, btw that Moltres is way to hard to catch... i battled it 10 or 9 times and still cant catch it ;(
