4.8 iOS app crash after splash screen

Hi everyone,
I tried to launch my game on iPhone 6 and it was working pretty well. Added a few assets more and now it crash on launch. I thought maybe the app was too heavy to run on iPhone (since it’s working well on iPad Air 2). But wince the app is 550 Mo (and my previous app was 900 and it was running good, don’t know if the size of the app can affect somehow, just telling) so i thought maybe it was something else.
I Got this crash log from the app but seriously… i don’t understand everything at it. So if someone could check and see if this tells anything helpful, that would help me a lot, thanks guys

Hiya, maybe you might want to try what was suggested in this thread, they had similar problem after importing some assets and seem to have found a solution
