Why my Clip.Create is not working at webgl when it works fine on other platforms

Below is my code, and I mainly want to create some clips with different pitches and store them in a list.

public class AudioClipPitchCreating : MonoBehaviour
{
    public AudioClip originalClip;
    public static List<AudioClip> AudioList = new List<AudioClip>();
    public float[] pitchLevels = {1, 1.2f, 1.4f,1.6f,1.8f,2f }; // different pitch version
    public AudioSource playMusic;

    int i = 0;
    void Awake()
    {
        playMusic.clip = originalClip;
        foreach (var pitch in pitchLevels)
        {
            AudioClip modifiedClip = AdjustPitch(originalClip, pitch);
            AudioList.Add(modifiedClip);
        }
        playMusic.Play();
    }

    AudioClip AdjustPitch(AudioClip clip, float pitch)
    {
     
        int samples = Mathf.CeilToInt(clip.samples / pitch);
        float[] data = new float[samples * clip.channels];
        clip.GetData(data, 0);


        float[] newData = new float[samples * clip.channels];
        for (int i = 0; i < samples; i++)
        {

            float sampleIndex = i * pitch;
            int index0 = Mathf.FloorToInt(sampleIndex);
            int index1 = Mathf.Min(index0 + 1, data.Length - 1);

            float t = sampleIndex - index0;
            newData[i] = Mathf.Lerp(data[index0], data[index1], t);
        }


        AudioClip newClip = AudioClip.Create("ModifiedClip", samples, clip.channels, clip.frequency, false);
        newClip.SetData(newData, 0);
        return newClip;
    }

    void Update()
    {
        if (Input.GetMouseButtonUp(0))
        {
            if (i == 4)
            {
                i = 0;
            }
            playMusic.clip = AudioList[i];
            playMusic.time = 10f;
            playMusic.Play();
            
            i++;
        }
    }
}

I have dragged the clip onto originalClip in the Unity editor. The clip creation works fine on the Windows etc platforms, but when I use WebGL. None of the clips has been created and I get the error below:

“Length of created clip must be larger than 0.”

I don’t understand why the length is not greater than 0 in WebGL when it works fine on other platforms.

Does anyone have an idea about this?

Thank you!

After some research, I really have no clue what’s going on with this issue. Does anyone have an idea and can help me?
