C:\Users\ABTR001\Desktop\upc_app\node_modules\react-native\Libraries\Core\ExceptionsManager.js:82 Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

Direzione di ricerca
Start by reproducing the failure with Expo 34 and react-native-debugger, then inspect the stack entries in RNDebuggerWorker.js and ReactFabric-prod.js alongside React Native's ExceptionsManager.js. Confirm the relevant compatibility issue and verify that the application starts without the registerEventHandler error.
