Has anyone passed supabase user to the tRPC context in Expo?

I am trying to pass the logged in user to the context of tRPC. To be able to use it in the routers and create a protected procedure. However, my application keeps on crashing as soon as I pass my user to the context (when a page is loaded where a call to the API is done). It looks like it has something to do with react-native-async-storage. Any ideas?
@react-native-async-storage/async-storage/lib/commonjs/AsyncStorage.js:63
return createPromise(() => window.localStorage.getItem(key), callback);
