React Native just crashes after splash screen

I was able to access the MacOS logs by going to spotlight and typing in console, clearing out the console and then observing it as I attempted to open the app within the simulator.

There will be a lot to look over as with most logs, but the error message that is a good starting point:

Terminating app due to uncaught exception 'RCTFatalException: Unhandled JS Exception: Cannot create styled-component for component: [object Object]', reason: 'Unhandled JS Exception: Cannot create styled-component for component: [object Object]

App Crashes on Splash Screen on Android 7 React Native

The issue has been solved, basically what I did earlier was that I Placed splash_screen.png in the drawable folder which worked perfectly for Android 7+ but was causing problems for Android 7 and lower.

So I placed the same splash_screen.png in all mipmaps folders and referred to mipmaps as follows in the launch_screen.xml file.

android:src="@mipmap/launch_screen"

After that splash screen worked perfectly for all the versions. Thanks
