White screen only in Xcode Emulator

Hi
My app was rejected from app store because of this problem.
"when launched the App for the first time only a blank screen is shown".

I've tried my app on ipad and iphone and it works correctly.
If I run the app on emulator from xcode remains stuck in white screen.

Xcode don't give me any error so I don't have an idea of how resolve the problem.
I've searched a lot on Google but nothing helped.

Someone else dealed with this problem?

I don't know if should help, my app was made with Ionic/Stencil + Capacitor. No problem on Android.
