That's actually strange, many people have reported crashes on Android after the party, while playing the game or after exiting the app and trying to open it again later. All these problems were solved by clearing the game cache or at least no one reported that it didn't help.
I know it might be funny, but try restarting your phone and clear the cache again, I'm pretty sure this should help with the issue you're facing.
Still dev will definitely try to find the root of the problem and fix it.
Hope it helps,
Cheers
