Character stucks under the ceiling when holding jump button

Hi, Im new to unity. Everytime I hold the jump button my character stucks under the ceiling. How can I fix this? I want that the character falls down, it should not stuck under the ceiling.

using UnityEngine;

public class Movement : MonoBehaviour
    private Rigidbody2D rb;
    public float speed = 10;
    public float Jumpforce = 10;
    private void Start()
        rb = GetComponent<Rigidbody2D>();

    private void FixedUpdate()
        var movement = Input.GetAxis("Horizontal");
        transform.position += new Vector3(movement, 0, 0) * Time.deltaTime * speed;

        if (Input.GetButton("Jump") && Mathf.Abs(rb.velocity.y) < 0.001f)
            rb.AddForce(new Vector2(0, Jumpforce), ForceMode2D.Impulse);

Hi @bertan234 !

I think you should try adding physic material to your character GameObject.
I assume there will be some internal AddForce calls or something like that.
See here about physic materials:

Hope this helps,
