Input.GetButtonDown("Jump") doesn't work

Hello. Space key doesn't work when I run the code. What could be the reason? By the way, the version I'm using is 2021.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerMovement : MonoBehaviour
 {   
     private float speed = 400f;
     private float jumpforce = 500f;
     private float OverlapBoxSize = 0.2f;
     public Transform FeetPos;
     Rigidbody2D Rigidbody;
     bool jumpPressed;
     
     void Start()
     {
         Rigidbody = GetComponent<Rigidbody2D>();
     }
 
     private void Update()
     {
         Collider2D col = Physics2D.OverlapBox(FeetPos.position, new Vector2(transform.localScale.x, OverlapBoxSize), 0, LayerMask.GetMask("Ground"));
         if(Input.GetButtonDown("Jump") && col)
         {
             jumpPressed = true;
         }
     }
     void FixedUpdate()
     {
         float HorizontalMovement = Input.GetAxisRaw("Horizontal");
         Rigidbody.velocity = new Vector2(HorizontalMovement*speed*Time.deltaTime, Rigidbody.velocity.y);
         if(jumpPressed == true)
         {
           Rigidbody.AddForce(new Vector2(0, jumpforce*Time.deltaTime), ForceMode2D.Impulse);
           jumpPressed = false;
         }
 
     }
 
     private void OnDrawGizmos()
     {
         Gizmos.color = Color.black;
         Gizmos.DrawWireCube(FeetPos.position, new Vector2(transform.localScale.x, OverlapBoxSize));
     }
 }
