I'm going to check if there's something wrong on my end. Nothing quite matches but I did get an update to coral island right after it crashed. I'll let you know of anything else happens.

Ah, thanks a lot for sharing the video! Can you let me know if this also happens after playing the Ring Toss minigame, or in other situations? 😮
