Cannot get pixels when webcam is not running, error. (Unity 2D)

Hey everybody!!!
I want to take a picture from my web camera but the programm decides that my camera is not running.
This is my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.IO;

public class Open_Camera : MonoBehaviour {

    public RawImage rawimage;
    private WebCamTexture webCam = null;
    
    void Start()
    {
        WebCamTexture webCam = new WebCamTexture();
        
        rawimage.texture = webCam;
        rawimage.material.mainTexture = webCam;
        
        webCam.Play();

   // I tried to use the function code inside Start() to test it, but all I get is a black picture.           
   //I think black picture is because it takes the picture before camera open.

        /*Texture2D photo = new Texture2D(rawimage.texture.width, rawimage.texture.height);
        photo.SetPixels(webCam.GetPixels());
        
        photo.Apply();
        
        byte[] bytes = photo.EncodeToPNG();
       
        File.WriteAllBytes("Assets/Samples/New Pics/" + "testing.png", bytes);
        counter++;
        */
    }

    private void Update()
    {
        WebCamTexture webCam = new WebCamTexture();
        if (Input.GetMouseButtonDown(0))
        {
            saveImage(webCam);
            webCam.Stop();
        }
    }

    string path = "A_path"; //this is not the path I use.
    int counter = 0;

    void saveImage(WebCamTexture x)
    {
 
        Texture2D photo = new Texture2D(rawimage.texture.width, rawimage.texture.height, TextureFormat.ARGB32, false);

        photo.SetPixels(x.GetPixels());
        Debug.Log("test");
        photo.Apply();

        byte[] bytes = photo.EncodeToPNG();

        File.WriteAllBytes("Assets/Samples/New Pics/" + (counter.ToString() + "testing.png"), bytes);
        counter++;
    }
}

Also when i run it I get Cannot get pixels when webcam is not running. Like something is closing my camera. Thnx for the help
