App crashes on launch with iOS 26 beta + React Native new architecture (TurboModule ObjC exception)

Describe the bug

App crashes on every launch when react-native-purchases is installed on iOS 26 beta with React Native new architecture enabled.

1. Environment

   1. Platform: iOS
   2. SDK version: react-native-purchases latest
   3. OS version: iOS 26.3.1 beta (23D771330a)
   4. Xcode version: 26.4
   5. React Native version: 0.83 (Expo SDK 55)
   6. SDK installation: CocoaPods
   7. How widespread: 100% crash rate on iOS 26 beta devices

2. The native module throws an ObjC exception during TurboModule registration at app startup — before any JavaScript runs. ObjCTurboModule::performVoidMethodInvocation → convertNSExceptionToJSError corrupts Hermes memory → SIGABRT / SIGSEGV. JS-side try-catch and dynamic imports have no effect since the crash happens at native module registration time, not during JS execution.

3. Steps to reproduce:

   • Expo SDK 55 / RN 0.83 project with new architecture enabled (cannot disable — required by react-native-reanimated 4.x)
   • Install react-native-purchases
   • Run on device or simulator with iOS 26 beta
   • App crashes immediately on launch every time

   Expected: App launches normally
   Actual: Immediate crash before first frame renders

4. Crash signature: ObjCTurboModule::performVoidMethodInvocation → objc_exception_rethrow → std::__terminate → SIGABRT

Additional context

New architecture cannot be disabled as react-native-reanimated 4.x calls assert_new_architecture_enabled() at build time. Full crash logs available on request.

Hey Jacob, Really appreciate the quick response but apologies on the tardiness from my end. Heres the key details:        ∙Expo SDK 55 / React Native 0.83        ∙iOS 26.3.1 beta (build 23D771330a) on iPhone 17 Pro ∙New Architecture enabled (required by react-native-reanimated 4.x) ∙Crash happens 100% of the time on physical device, never in simulator ∙Root cause identified: performVoidMethodInvocation calls convertNSExceptionToJSError from native invoker thread, corrupting Hermes memory ∙Fix exists in facebook/react-native#56265 but hasn’t been backported to 0.83 yetAttached is the latest crash log if you deem it helpful:Happy to test any beta fixes you ship.Again, appreciate the help! ChadSent from my iPhoneOn Apr 1, 2026, at 6:38 PM, Jacob Rakidzich ***@***.***> wrote:JZDesign left a comment (RevenueCat/react-native-purchases#1712) Hey!
