graveopener

I been playing the game for a couple of months now and I like the game quite a lot. I got an issue that started yesterday and today. When I open the game it just crashes and by that I mean not even the loading screen opens just like that first image and even if I leave it like that for many minutes it doesnt change. It was working really well until yesterday. I did the pre-download and all the things and Im sure the game is updated, and I have a pretty good phone that I play it on. Could you please help me or advise me on what to do next.
