Crash on generating video from photos & audio.

I am facing one crash of array index out of range while creating the video from one audio & multiple images.

@IBAction func proccedButtonHandler(sender: UIButton) {
if let audioURL4 = Bundle.main.url(forResource: "Barish2" , withExtension: "mp3") {
VideoGenerator.current.generate(withImages: self.images ?? [], andAudios: [audioURL4], andType: .singleAudioMultipleImage) { (progress) in
print(progress)
} outcome: { (result) in
switch (result) {
case .success(let url):
print("URL: ", url)

            case .failure(let error):
                print(error)
            }
        }

    } else {
        print("Mising audio file")
    }
}

Crash line is:
Line: 178: imageForVideo = VideoGenerator.current.images[frameCount]
File: VideoGenerator.swift

What I observed is, the VideoGenerator.current.images are setting to 0. I am not able to find why the sent images are relinquished.

Hi @Naresh6885
Please check your audio file is proper or not in my case audio file was not proper so that's why I was getting this crash

Please check the size of audio file
