Hello @khaled-muhammad We have tried to replicate the same issue with ios 15.5, and we cannot reproduce the same. Please recheck the same with our latest release and let us know if you still face the same?

Problem solved.

Use 'test.m4a' instead of

File file = File('test.mp3');

@JeChingLin Can you please provide sample code for how you were trying to play the audio?

[awnigharbia]

this is work for me.

Recorder

 bool _isRecording = false;
 late final RecorderController recorderController = RecorderController();

 Future<void> _startRecord() async {
    try {
      if (await recorderController.checkPermission()) {
        if (Platform.isAndroid) {
          await recorderController.record();
        } else {
          appDirectory = await getTemporaryDirectory();
          final file = File('${appDirectory.path}/record.m4a');
          await recorderController.record(file.path);
        }

        setState(() {
          _isRecording = recorderController.isRecording;
        });
      }
    } catch (e) {
      if (kDebugMode) {
        print(e);
      }
    }
  }

Player

   late final PlayerController playerController;
   late Directory appDirectory;
   late PlayerState state = PlayerState.stopped;

    @override
     void initState() async {
         super.initState();
         appDirectory = await getTemporaryDirectory();
         final file = File('${appDirectory.path}/tmp.m4a');
         await file.writeAsBytes(widget.bytes);
   
         try {
             await playerController.preparePlayer(file.path);
             setState(() {
                 state = playerController.playerState;
              });
          } catch (e) {
              if (kDebugMode) {
                  print('player error: $e');
              }
          }
      }

You shouldn't be facing the crash from 1.0.0. the native initialization of the player was force unwrapped that's why it was throwing exception sometimes. I'm going to close this issue for now but feel free to reopen or create a new issue.
