I am trying to change the fov of my camera when left control is pressed, but it won't work

using System.Collections.Generic;
using UnityEngine;

public class FOVCameraChange : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if(Input.GetKey(KeyCode.LeftControl)){
            Debug.Log("DOWN");
            Camera.main.fieldOfView = 120;
        }
        else {
            Debug.Log("UP");
            Camera.main.fieldOfView = 60;
        }
    }
}

The error I am getting is "Object Reference not set to an instance or an object."

I am trying to make the camera fov double when you press control.

Camera.main returns the first (enabled) camera that has the tag "MainCamera". Since it's throwing an NRE, you must not have a camera with that tag within your scene. Either give your camera the "MainCamera" tag, or make a Camera variable and set it through the editor, the same as you would do any other variable:

public class FOVCameraChange : MonoBehaviour
{
    [SerializeField] private Camera camera;

    // Update is called once per frame
    void Update()
    {
        if(Input.GetKey(KeyCode.LeftControl)){
            Debug.Log("DOWN");
            camera.fieldOfView = 120;
        }
        else {
            Debug.Log("UP");
            camera.fieldOfView = 60;
        }
    }
}

Unity Scripting API: Camera.main
