Screenshots and Videos

No response

Start with the failure at ReactNativeFeatureFlagsCxxInterop.kt:28 and the load path through DefaultNewArchitectureEntryPoint.load and ReactNativeApplicationEntryPoint.loadReactNative. Reproduce a production build on Android 11 or 12, then inspect whether libreactnative.so is present in the APK and the SoLoader sources shown in the stack trace. Done means the app starts without SoLoaderDSONotFoundError.
