Character Jumps Too High of edges

I am having this problem where the player jumps 2x-3x as high as he should if he jumps of a platform/Ground edge. I am not sure why he does that. Here is the code.

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
[Header(“Moving”)]
[SerializeField] private float moveSpeed;

[Header("Jumping")]
[SerializeField] private KeyCode jumpKey = KeyCode.Space;
[SerializeField] private float jumpHeight;

[Header("Gravity Scales")]
[SerializeField] private float normalGravityScale;
[SerializeField] private float fallGravityScale;

[Header("Ground Check")]
[SerializeField] private LayerMask groundLayer;
[SerializeField] private Transform groundCheck;
[SerializeField] private float raySize;

private float horizontalInput;

private Rigidbody2D rb;

private bool isFacingRight = true;

[Header("Cayote Time")]
[SerializeField] private float cayoteTime;
private float cayoteTimeCounter;



private void Start()
{
    Cursor.visible = false;
    rb = GetComponent<Rigidbody2D>();
}

private void Update()
{
    horizontalInput = Input.GetAxisRaw("Horizontal");

    if (horizontalInput < 0 && !isFacingRight || horizontalInput > 0 && isFacingRight)
    {
        Flip();
    }

    if (rb.velocity.y >= 0)
    {
        rb.gravityScale = normalGravityScale;
    }
    else if (rb.velocity.y <= 0)
    {
        rb.gravityScale = fallGravityScale;
    }

    if (isGrounded()){
        cayoteTimeCounter = cayoteTime;
    }else{
        cayoteTimeCounter -= Time.deltaTime;
    }

}

private void FixedUpdate()
{
    MovePlayer();

    if (Input.GetKeyDown(jumpKey) && cayoteTimeCounter > 0f)
    {
        Jump();
    }
}

private void MovePlayer()
{
    rb.velocity = new Vector2(horizontalInput * moveSpeed, rb.velocity.y);
}

private void Jump()
{
    float jumpForce = Mathf.Sqrt(jumpHeight  * -2 * (Physics2D.gravity.y * rb.gravityScale));
    rb.AddForce(new Vector2(0, jumpForce), ForceMode2D.Impulse);
}

private void Flip()
{
    Vector3 currentScale = gameObject.transform.localScale;
    currentScale.x *= -1;
    gameObject.transform.localScale = currentScale;

    isFacingRight = !isFacingRight;
}

private bool isGrounded()
{
    Vector2 rayPos = groundCheck.position;
    Vector2 rayDir = Vector2.down;

    RaycastHit2D hit = Physics2D.Raycast(rayPos, rayDir, raySize, groundLayer);

    if (hit.collider != null){
        return true;
    }
    return false;
}

}

I would flip that around. Do the math in fixedupdate() and move your input controls to the Jump(). If I’m right, you want to do all your rigidody physics in Fixed Update.
