Invoke not working

[Kontroll]

I’m getting an error Trying to Invoke method: CollisionHandler.ReloadLevel couldn’t be called.
I know I should paste the code in a code block but wanted to show the problems shown in the tab about ReloadLevel being declared but never used

Here is my code block

using UnityEngine;
using UnityEngine.SceneManagement;

public class CollisionHandler : MonoBehaviour
{
    void OnCollisionEnter(Collision other) 
    {
        switch (other.gameObject.tag)
        {
            case "Friendly":
                Debug.Log("You've hit a friendly object!");
                break;
            case "Finish":
                LoadNextLevel();
                Debug.Log("You've finished the level!");
                break;
            case "Fuel":
                Debug.Log("That's fuel. You need that");
                break;
            default:
                Invoke("ReloadLevel" , 1f);
                break;
        }

    void ReloadLevel()
        {
            int currentSceneIndex = SceneManager.GetActiveScene().buildIndex;
            SceneManager.LoadScene(currentSceneIndex);
        }

    void LoadNextLevel()
        {
            int currentSceneIndex = SceneManager.GetActiveScene().buildIndex;
            int nextSceneIndex = currentSceneIndex + 1;
            if (nextSceneIndex == SceneManager.sceneCountInBuildSettings)
            { 
                nextSceneIndex = 0;
            }
            SceneManager.LoadScene(nextSceneIndex);
        }
    }
}

It’s because you have ReloadLevel as a local function. It cannot be a local function. Move it outside of the OnCollisionEnter block
