[SOLVED] Disconnecting headphones with audiokit running gives malloc error with AKOperationEffect specifically

Disconnecting headphones with audiokit running gives malloc error with AKOperationEffect specifically

// My code is below

do{
    file = try AKAudioFile(readFileName: "Sound1.mp3", baseDir: .resources)
    //    file =  try AKAudioFile(forReading: SingletonClass.sharedInstance.recordedURLs[SingletonClass.sharedInstance.recordedURL]!)

    //     AKSettings.defaultToSpeaker = true
}
catch {

}

do {
    player = try AKAudioPlayer(file : file)

}
catch {

}

let lfoAmplitude = 1_000
let lfoRate = 1.0 / 3.428

_ = 0.9

//filter section effect below
filterSectionEffect = AKOperationEffect(tracker) { input, _ in
    let lfo = AKOperation.sineWave(frequency: lfoRate, amplitude: lfoAmplitude)
    return input.moogLadderFilter(cutoffFrequency: lfo + cutoffFrequency,
                                  resonance: resonance)
}
Audiokit.output = filterSectionEffect
Audiokit.start()

And whenever I play the audio using a button with code player.play , the audio gets played properly. And if I connect the headphones, it gets played properly as well but as soon as I disconnect the headphones, I see the error:

It happens in same way for both wired as well as bluetooth headphones. My app with stuck because of this issue only that too happens only with AKOperationEffect. Any help would be appreciated.
