Realm white screen in React Native

Good Morning,
I’m using Realm in React Native, however when I add a new field in my schema, when generating a new release version of my app, it will have a white screen.
Does anyone know how to solve?
I’m changing the SchemaVersion just right.

@Mobile_Syntesis We will need more information from you. Like what schema you have, what schema you are migrating to, how you migrate, and then the error you get when you run your current set-up

This happens to me a lot and I still don’t know exactly why. I usually end up just undoing my changes to the schema until it works and then trying to make them again one by one. I’ve noticed it sometimes (maybe always?) happens when I try to make properties optional.
