My Expo app crashes immediately when started in TestFlight. The app is working correctly in --no-dev mode.

Side note: the application had some uncaught exception originating from SplashScreen handling but that seems to have disappeared by moving SplashScreen.preventAutoHideAsync(); outside the app entry point class.

I’ve set the ErrorUtils.setGlobalHandler handler to muting all errors.

How can I come to better understanding of where the problem is to be able to fix it?
