iOS crash in production-only

[ervibern]

Hi! I'm using Expo managed workflow. I'm importing an .obj file and rendering as shown below.
In the development build with a physical device, animation works very well.
When I shipped the build to TestFlight and installed on multiple iOS devices, all crashed when trying to load the 3D model. How should I start debugging this issue? Maybe someone had encountered similar problems?

I use the following packages:

    "expo": "~47.0.14",
    "expo-gl": "~12.0.1",
    "react-native": "0.70.8",
    "r3f-native-orbitcontrols": "^1.0.5",
    "three": "^0.145.0",
    "@react-spring/three": "^9.7.2",
    "@react-three/drei": "^9.65.3",
    "@react-three/fiber": "^8.12.0",
    "react-native-reanimated": "~2.12.0",

The structure of the code is like this:

  const material = useLoader(MTLLoader, require('../assets/models/3Dmodel.mtl'));
  const obj = useLoader(
    OBJLoader,
    require('../assets/models/3Dmodel.obj'),
    (loader) => {
      material.preload();
      loader.setMaterials(material);
    }
  );
  
  return (
          <Canvas camera={camera} style={{ width: windowWidth, alignSelf: 'center' }}>
            <a.perspectiveCamera rotation-y={springRotation} rotation-x={springRotation}>
              <ambientLight intensity={AMBIENT_LIGHT_INTENSITY} />
              <pointLight intensity={LIGHT_INTENSITY} position={LIGHT_POSITION} castShadow />

              <ContactShadows
                resolution={512}
                position={[0, -2.3, 0]}
                opacity={0.4}
                scale={10}
                blur={2.5}
                far={8}
              />

              <OrbitControls enablePan={false} enableZoom={false} rotateSpeed={0.5} />
              
              <Suspense fallback={null}>
                  <a.mesh
                       ref={mesh}
                       scale={active ? 1.2 : 1}
                       onClick={() => rotateCamera()}
                       onDoubleClick={() => toggleActive()}>
                       <primitive object={obj} scale={4} />
                  </a.mesh>
              </Suspense>
            </a.perspectiveCamera>
          </Canvas>
  );

The error I retrieved in XCode:

Would appreciate any help! 🤝
