Object reference not set to an instance of an object with raycast2d

Hello! So i see many people posting about the same error but not with my exact needs. So I am currently learning Unity and thus im playing around with stuff. My Plan is to make a one way platform that lets you fall through after you stand on it and press a serten key. The good thing is, it works but globally. I then proceeded to look into raycasts and tried to use them to detect, wether im on such a platform or not. Another good thing it also works! but now is the bad thing. Everytime I am in midair and press S i get the NullReferenceException: Object reference not set to an instance of an object. This is the exact error

now to my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class VerticalPlatform : MonoBehaviour
 {
 
     public static PlatformEffector2D effector;
     public static float waitTime;
 
     private bool platformRequest = false;
 
     // Start is called before the first frame update
     void Start()
     {
         effector = GetComponent<PlatformEffector2D>();
     }
 
     // Update is called once per frame
     void Update()
     {
         //THIS IS THE LINE 22 ERROR
         Fall();
     }
 
     public static void Fall()
     {
         if (Input.GetKeyUp(KeyCode.S))
         {
             waitTime = 0.5f;
         }
         //THIS IS THE LINE 31 ERROR
         if (Input.GetKeyDown(KeyCode.S) && PlayerController.checkForPlatform.transform.tag == "Platform")
         {
             if (waitTime <= 0)
             {
                 effector.rotationalOffset = 180f;
                 waitTime = 0.5f;
             }
             else
             {
                 waitTime -= Time.deltaTime;
             }
         }
         if (Input.GetKey(KeyCode.Space))
         {
             effector.rotationalOffset = 0;
         }
     }
 }

The thing to note is, that i use the raycast on my Playercontroller script wich sits in the update function like this: checkForPlatform = Physics2D.Raycast(groundCheck.position, Vector2.down, 2f);

I declared the variable up top as public static RaycastHit2D checkForPlatform;

Now why does it spam this error even tho it works just fine?
