react-native-firebase freezes app on splash screen

Question

I followed all the instructions on https://rnfirebase.io/ for installing firebase, but my app still freezes on splash screen

I have no error message because the issue only occurs once the app is built in .app file (expo build:ios), all works fine when testing (expo run:ios)

MyFirebaseScript.js

import remoteConfig from "@react-native-firebase/remote-config";
// only the import is causing the problem
// same issue with firestore, ...
