Game crashed on IOS

Hi everyone, I have a problem when I try to export my game to Iphone. (using 3.4.5)

The game runs fine android and the editor. But when I export it on mac, it gives the following message, then it crashes on the iphone.

''Application windows are expected to have a root view controller at the end of application launch''

A lot people say that is cause by the prime31 Etcetera Plugin, but I don't have it in my project.

Prime31 plugin I have got in my project:

IAB , StoreKit, SocialNetworking (both Android and IOS), Chartboost (Android only)

And I got them on Asset Store very recent. I also used the update button to import new stuff.

Please help if you have any idea. Thank you very much.
