Can't jump on tilemap

Hi guys,
I have a problem. My character is stuck on jump animation and can't jump when he is on Tilemap Collider 2D. I changed this to 2 box colliders but it's still not working.

Here is how it looks:

Here is code with player input:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Player_Input : MonoBehaviour
6. {
7.     public static bool isJumpPressed = false;
8.     public static float movementInput;
9.     public static Vector3 localMousePosition;
10.     public static Transform playerTransform;
11.     private Animator playerAnim;
12.  
13.     private void Start()
14.     {
15.         playerTransform = GetComponent<Transform>();
16.         playerAnim = GetComponent<Animator>();
17.     }
18.  
19.     void Update()
20.     {
21.         movementInput = Input.GetAxis("Horizontal");
22.  
23.         if (movementInput != 0f)
24.         {
25.             playerAnim.SetFloat("Speed", 0.2f);
26.         }
27.         else
28.         {
29.             playerAnim.SetFloat("Speed", 0f);
30.         }
31.  
32.  
33.         localMousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
34.  
35.         if (Input.GetButtonDown("Jump"))
36.         {
37.             isJumpPressed = true;
38.         }
39.     }
40. }
41.  

And here is code with physics:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using static Player_Input;
5.  
6. public class Player_Physics : MonoBehaviour
7. {
8.     [SerializeField] private LayerMask platformLayerMask;
9.     [SerializeField] private Transform groundCheck;
10.  
11.     private Rigidbody2D playerBody;
12.     private Collider2D playerCollider;
13.     private SpriteRenderer playerSprite;
14.     private Animator playerAnim;
15.  
16.  
17.  
18.     [SerializeField] private float playerSpeed = 40f;
19.     [SerializeField] private float jumpHeight = 2f;
20.  
21.     // Start is called before the first frame update
22.     void Start()
23.     {
24.         playerBody = GetComponent<Rigidbody2D>();
25.         playerCollider = GetComponent<BoxCollider2D>();
26.         playerSprite = GetComponent<SpriteRenderer>();
27.         playerAnim = GetComponent<Animator>();
28.  
29.     }
30.  
31.     private void Update()
32.     {
33.         if (isGrounded())
34.         {
35.             playerAnim.SetBool("isJumping", false);
36.         }
37.         else if(!isGrounded())
38.         {
39.             playerAnim.SetBool("isJumping", true);
40.         }
41.     }
42.  
43.     void FixedUpdate()
44.     {
45.         playerBody.velocity = new Vector2(movementInput * Time.deltaTime * playerSpeed, playerBody.velocity.y);
46.  
47.         Debug.Log(playerBody.velocity);
48.  
49.         if (playerBody.velocity.x < 0)
50.         {
51.             playerSprite.flipX = true;
52.         }
53.         else if (playerBody.velocity.x > 0)
54.         {
55.             playerSprite.flipX = false;
56.         }
57.  
58.         bool onGround = isGrounded();
59.  
60.  
61.         if (isJumpPressed && onGround)
62.         {
63.                 playerBody.AddForce(new Vector2(0, jumpHeight), ForceMode2D.Impulse);
64.                 isJumpPressed = false;
65.         }
66.     }
67.  
68.     private bool isGrounded()
69.     {
70.         return Physics2D.OverlapBox(groundCheck.position, new Vector2(playerCollider.bounds.size.x, 0.01f), 0f, platformLayerMask);
71.     }
72. }
73.  

 

I assume would that your tilemap is on a different layer to the one you are checking to see if the player is grounded.
