🐛 App crashes (iOS 18.1) when user stops recording video. AVFCapture: CameraSession.deactivateAudioSession()

What's happening?

When user stops recording a video, app crashes. The error log from XCode shows the following (see image)

This happened when we upgraded to version 4.5.2 of the library. The error seems to be happening in the Swift CameraSession+Audio.swift file

final func deactivateAudioSession() { VisionLogger.log(level: .info, message: "Deactivating Audio Session...")

audioCaptureSession.stopRunning()
VisionLogger.log(level: .info, message: "Audio Session deactivated!")

}

This was working fine before we upgraded to RN 0.75 with react-native-vision-camera v. 4.5.2

Reproduceable Code

import {Camera, getCameraDevice} from 'react-native-vision-camera';
...
const stopRecordingVideo = async () => {
    try {
      setIsRecording(false);
      console.log('stopRecordingVideo');
      timerService.stopTimer();
      await camera?.current?.stopRecording();
      setRemainingSeconds(botbVideoLength);
    } catch (error) {
      console.warn(error);
      Alert.alert('Error', error?.cause?.message);
    }
  };
...

Guten Tag, Hans here! 🥨

Thanks for reporting this issue. It seems like you might be facing a crash when stopping the video recording. However, to better assist you, could you please provide more detailed logs from Xcode? Specifically, look for any runtime errors in ze console window to help us diagnose zhis issue more effectively.

Also, make sure to check if zhese issues can be replicated in a basic example with only ze vision camera functionality, as it might help in pinpointing onde the problem lies.
