React Native New Architecture: Troubleshooting Bridgeless Mode Interop Crashes

  The React Native ecosystem is undergoing its most significant shift since its inception. With the New Architecture (Fabric and TurboModules) maturing, the framework is moving toward   Bridgeless Mode —a state where the legacy JavaScript bridge is entirely removed. While this promises faster startups and synchronous native interfacing, it introduces a critical breaking change. Legacy Native Modules that rely on the  RCTBridge  or  ReactContextBaseJavaModule  without JSI bindings will fail. If you are seeing  Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'X' could not be found  or generic  EXC_BAD_ACCESS  crashes during app initialization, your application is suffering from an Interop Layer failure. This guide provides the root cause analysis and the technical implementation to resolve these crashes in a Bridgeless environment. The Root Cause: Why Legacy Modules Break To fix the crash, you must understand the architecture g...
