Error with Image subscriber

[raucal]

I am having an error with the subscriber to a topic that publishes messages in sensor_msgs/Image format. This error only occurs when I implement it in Hololens 2. In Unity it works correctly. Attached is the Visual Studio console error and the subscriber script:

Script:

using UnityEngine;
using UnityEngine.UI;

namespace RosSharp.RosBridgeClient
{
[RequireComponent(typeof(RosConnector))]
public class ImageSubscriber : Subscriber<Messages.Sensor.Image>
{
public MeshRenderer meshRenderer;

    private Texture2D texture2D;
    private byte[] imageData;
    private bool isMessageReceived;
    public GameObject raw;
    private int width, height;

    protected override void Start()
    {
		base.Start();
        texture2D = new Texture2D(1, 1);
        meshRenderer.material = new Material(Shader.Find("Standard"));
    }
    private void Update()
    {
        if (isMessageReceived)
            ProcessMessage();
    }

    protected override void ReceiveMessage(Messages.Sensor.Image Image)
    {
        width = (int)Image.width; // Ancho de la imagen (número de filas)
        height = (int)Image.height;
        imageData = Image.data;
        isMessageReceived = true;
    }

    private void ProcessMessage()
    {
        //texture2D = new Texture2D(width, height, TextureFormat.RGB24, false);
        texture2D.LoadImage(imageData);
        texture2D.Apply();
        meshRenderer.material.SetTexture("_MainTex", texture2D);
        raw.GetComponent<RawImage>().texture = texture2D;
        isMessageReceived = false;
    }

}
