Minimal reproducible example

Steps to reproduce

I am experiencing a consistent native crash (SIGSEGV) on Android in Release/Preview builds when rendering a basic @react-three/fiber scene. The crash occurs during the WebGL renderer initialization within libexpo-gl.so.

This issue is reproducible in a minimal standalone project and seems to be related to expo-gl's interaction with the JS runtime (Hermes) in production builds.

Steps to Reproduce
1.Clone the minimal reproduction repository
2.Install dependencies
3.Generate the Android native project npx expo prebuild -p android --clean
4. Build the release APK (crash does not reliably reproduce in development or in expo go): cd android && ./gradlew :app:assembleRelease
5.Install and launch on a physical device

Expected Behavior

The app should launch and render the simple 3D scene (e.g., a rotating cube) without crashing the native layer.
Actual Behavior

The app crashes immediately upon startup (or when the GL view initializes) with a native segmentation fault.

Crash Log:
