🐛 App Crashed While camRef.current.takePhoto() in React Native New Architechture

[Vigneshwaran-crypto]

What's happening?

    const file = await cameraRef.current.takePhoto({
      qualityPrioritization: 'quality',
      flash: 'off',
      enableShutterSound: false,
    });

Reproduceable Code

const camType = useCameraDevice('back', {
    physicalDevices: ['wide-angle-camera'],
  });

  const camFormat = useCameraFormat(camType, [{photoResolution: 'max'}]);

  const cameraRef = useRef(Camera);


      <Camera
          ref={cameraRef}
          device={camType}
          format={camFormat}
          style={{height: 300, width: 300}}
          isActive={true}
          photo={true}
          onError={err => LOG('camera error :', err)}
          onInitialized={() => LOG('camera onInitialized')}
        />

Can you reproduce this issue in the VisionCamera Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

Additional information

• I am using Expo
• I have enabled Frame Processors (react-native-worklets-core)
• I have read the Troubleshooting Guide
• I agree to follow this project's Code of Conduct
• I searched for similar issues in this repository and found none.

@Vigneshwaran-crypto I've never seen a useRef used like this for this package: const cameraRef = useRef(Camera);. I believe your issue may be that the ref should be called as const cameraRef= useRef<Camera | null>(null)

I am using vision camera with react-native v73 and expo 50 and it takes a picture perfectly.
