  You have flipped the switch. You enabled   newArchEnabled   in your   gradle.properties   and   Podfile , perhaps even set   bridgelessEnabled   to true in your Expo config. The build succeeds, but the moment the app launches, it crashes with a red screen (or silent native crash) pointing to: Uncaught Error: TurboModuleRegistry.getEnforcing(...): 'X' could not be found. This is the most common blockade when migrating to React Native 0.74+ and the New Architecture. It indicates a severance between your JavaScript Interface (JSI) expectations and the underlying native bindings. The Root Cause: Synchronous JSI vs. Asynchronous Bridge To fix this, you must understand the architectural shift. In the  Old Architecture ,  NativeModules.MyModule  was a proxy object. If the native module failed to load, the proxy might just be empty, or calls would fail silently across the asynchronous bridge. In the  New Architecture (Bridgeless) , w...

  If you are migrating to or starting a fresh project with Expo Router v4, you have likely encountered the "White Screen of Death" or the console screaming   Maximum update depth exceeded . This usually occurs when implementing protected routes. You follow the documentation, set up a  useEffect  to check for a user session, and issue a  router.replace() . Suddenly, your app enters a render loop, or deep links fail to resolve because the navigation state isn't ready when the auth check fires. Here is the root cause analysis and a production-grade implementation to handle authentication flows without race conditions. The Root Cause: Fighting the Navigation Cycle The infinite loop happens because of a conflict between React's render cycle and the Router's navigation lifecycle. The Trigger:  Your Root Layout mounts. The  useEffect  fires, detects no user, and calls  router.replace('/login') . The Action:  The router unmounts the current scre...
