"react-native-reanimated": "^2.9.0",

This is not compatible with Realm v10 on Android. We have a release candidate for v11.

Can you try:

npm install realm@11.0.0-rc.0

@fukemy That code looks fine. I’m going to follow up with some questions.

Can you try and implement the fallback property on the RealmProvider? This makes sure the children are not rendered until the realm context is set. The following example should suffice:

return (
    <RealmProvider fallback={() => null}>
...
</RealmProvider>

Are you using realm in any other way outside of the useRealm hook? If you, for example, open and close a realm within a useEffect then this would also close the realm returned from the useRealm hook.
