(MCPE) Startup crash

Okay first things first I'm just going to say add ipad 5th generation to the list that's what I use but now I can't set it as that... now that that's out of the way to the bug... I was trying to change my skin to a custom skin I downloaded... Then the game crashed I didn't think much of it, I just thought okay that's strange I will just relaunch... To my dismay it crashed on startup... I've refreshed the app I've hard rebooted my device, nothing. I've tried everything except deleting the app because I don't want to lose all my worlds...

 

 

The image is the skin I was trying to use... the video is is the crash loop it just freezes there for a split second and then it brings me to my home screen
