App crashes on launch - iOS 26.4.2 - React Native TurboModule bug - Guideline 2.1(a) rejection

Hello Apple Developer community,

I am seeking help with a recurring App Store rejection under Guideline 2.1(a) - Performance - App Completeness. My app crashes on launch specifically on iOS 26.4.2 and I have confirmed this is a platform-level bug in React Native — not an issue with my application code.

BACKGROUND My app is Highway Exit Food Finder — a navigation utility built with Expo SDK 55 / React Native 0.83. It has been in review for several weeks and has been rejected multiple times due to a crash on launch on iPad Air M3 and iPhone 17 Pro Max running iOS 26.4.2.

THE CRASH Every crash log shows the same signature:

Exception: EXC_CRASH (SIGABRT) Location: ObjCTurboModule::performVoidMethodInvocation Thread: com.meta.react.turbomodulemanager.queue

The crash occurs during TurboModule initialization — BEFORE any JavaScript code runs. This means no application-level code change can fix it.

CONFIRMED PLATFORM BUG This crash is documented in:

  • github.com/facebook/react-native/issues/54859
  • github.com/expo/expo/issues/44680

These issues confirm that React Native's New Architecture TurboModule system throws an NSException during async void method invocation on iOS 26 that cannot be caught, causing SIGABRT.

WHAT I HAVE TRIED

  1. Removed expo-notifications (possible crash source)
  2. Removed react-native-maps
  3. Simplified all screens to static components
  4. Set newArchEnabled: false in app.json
  5. Upgraded to Expo SDK 55
  6. Submitted 17+ builds attempting to fix this

Despite all these changes the crash signature remains identical across all builds because the crash happens at the platform level.

MY QUESTIONS

  1. Has anyone successfully gotten a React Native Expo app approved on App Store Review while running iOS 26.4.2 on review devices?

  2. Is there a known working configuration for Expo SDK 55 that avoids the TurboModule crash on iOS 26?

  3. Has anyone successfully appealed a 2.1(a) rejection caused by a platform bug rather than app code?

  4. Can Apple review devices be updated to use a stable iOS version for reviewing React Native apps while the iOS 26 compatibility issues are resolved?

DEVICE AND BUILD INFO

  • Review device: iPad Air 11-inch M3
  • OS: iPadOS 26.4.2
  • Framework: Expo SDK 55 / React Native 0.83
  • Build tool: EAS Build
  • All crash logs reference the identical TurboModule crash signature

Any help or guidance from the community or Apple engineers who monitor these forums would be greatly appreciated.

Thank you.
