libc++abi.dylib: terminating with uncaught exception of type NSException, React Native iOS

Issue Description::

I am working on react-native-ios app, most of the times it stuck after splash. I have created a duplicate splash screen inside my react native code. When app started I am redirecting it to dummy splash screen which is exactly like a splash. Here I am loading complete required data of app from API. After loading complete data I am pushing it initial screen. But most of the time my stuck after splash screen, or sometimes crash after loading splash(when moving from original splash to dummy splash screen where I am loading whole app required data).

There is no error inside terminal, I am getting this following mentioned error inside xcode output window, whenever my app crashed or when app stuck on splash screen.

Error::

• Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Application windows are expected to have a root view controller at the end of application launch'

• libc++abi.dylib: terminating with uncaught exception of type NSException

My iOS app working working fine if I am redirecting to login screen, but having issue whenever i am redirecting to dummy splash. I have also changes my dummy screen name to "initializer.js" but nothing happened. iOS app crashed or stuck after splash it redirecting it to screen where i am loading complete required data for app.
