Screen position out of view frustum error on FOV change?

So I have a zoom script, here it is:

(Javascript) private var baseFOV : float; public var speedIn : float; public var speedOut : float; public var newFOV :float;

 function Start () {
     baseFOV = Camera.main.fieldOfView;
 }
        
 function Update () {
     if (Input.GetMouseButton(1))
     {
         Camera.main.fieldOfView = Mathf.Lerp(Camera.main.fieldOfView,newFOV,Time.deltaTime*speedIn);  
         Time.timeScale = 0.4f;
         Time.fixedDeltaTime = 0.02f * Time.timeScale;
     }
       
     else {
         Camera.main.fieldOfView = Mathf.Lerp(Camera.main.fieldOfView,baseFOV,Time.deltaTime*speedOut); 
         Time.timeScale = 1;
         Time.fixedDeltaTime = 0.02f * Time.timeScale;
         
     }
 }

I'm using the FPS Controller too btw, this is an aim script. It slows the game while it is zoomed, one thing I noticed is that if I spam "P" (which is my pause aka Time.timeScale = 0;), then the screen goes white besides my pause splash screen and the error comes. I've tried resetting the scene thing and all those things, it isnt a bug I dont think, Im pretty sure it is a real error and if anyone has any info or help please provide it, thank you!

P.S. Here is my pause script if that is needed: (C#)

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityStandardAssets.Characters.FirstPerson;
 
 public class PauseGame : MonoBehaviour
 {
     
     private FirstPersonController myControl;
     public GameObject m9;
     public GameObject PauseThing;
     public GameObject music;
     private bool onoff;
 
 
 
 
 
 
     private void Awake()
     {
         myControl = GameObject.Find("FPSController").GetComponent<FirstPersonController>();
     }
 
     
 
     void Start()
     {
         PauseThing.SetActive(false);
 
     }
 
     void Update()
     {
         PauseTheGame();
     }
 
     
 
 
     void PauseTheGame()
     {
         if (Input.GetKeyDown("p"))
         {
             onoff = !onoff;
 
             if (onoff)
             {
                 Time.timeScale = 0;
                 myControl.m_MouseLook.XSensitivity = 0;
                 myControl.m_MouseLook.YSensitivity = 0;
                 m9.SetActive(false);
                 music.SetActive(false);
                 PauseThing.SetActive(true);
    
 
 
 
             }
 
             else
             {
                 Time.timeScale = 1;
                 myControl.m_MouseLook.XSensitivity = 2;
                 myControl.m_MouseLook.YSensitivity = 2;
                 m9.SetActive(true);
                 music.SetActive(true);
                 PauseThing.SetActive(false);
 
 
             }
         }
         if (Input.GetKey(KeyCode.Escape))
         {
             Time.timeScale = 1;
             myControl.m_MouseLook.XSensitivity = 2;
             myControl.m_MouseLook.YSensitivity = 2;
             m9.SetActive(true);
             music.SetActive(true);
             PauseThing.SetActive(false);
             
 
 
         }
 
         
 
 
       
         }
 
     
 
     
 
 }
