This is the error occurring :-

NullReferenceException: (null) UnityEngine.MonoBehaviour.StopCoroutine (UnityEngine.Coroutine routine) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/MonoBehaviourBindings.gen.cs:99)

This is the code :-

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Test : MonoBehaviour {

public GameObject Testobject;

public GameObject Main_Menu;
public Material[] TestShaders;
public Texture[] TestTextures;
public Texture[] TestPatterns;
public Color[] TestColors;

int m;

//To Change Menus 
public void Change_Menus(int x)
{
    for (int y = 1; y < Main_Menu.transform.childCount; y++) 
    {
        Main_Menu.transform.GetChild(y).gameObject.SetActive (false);
    }
    Main_Menu.transform.GetChild (x).gameObject.SetActive (true);

    x = m;
}
//To Function Shader 
public void Function_Shader_Menus(int x)
{
    Testobject.GetComponent<Renderer> ().material = TestShaders[x];
}
//To Function Texture
public void Function_Texture_Menus(int x)
{
    Testobject.GetComponent<Renderer> ().material.mainTexture = TestTextures[x];
}
//To Function Pattern
public void Function_Pattern_Menus(int x)
{
    Testobject.GetComponent<Renderer> ().material.mainTexture = TestPatterns[x];
}
//To Function Pattern Color 
public void Function_Pattern_Color_Menus(int x)
{
    Testobject.GetComponent<Renderer> ().material.color = TestColors[x];
}

}
