Hello i hope some unity professional is reading this but idk why unity is being a complete idiot

    float Horizontal;
    float vertical;
    Rigidbody2D rb;
    public bool facingRight=true;
    Animator anim;
    public Vector3 Ya;
    public bool knockback;
    public float timer;
    // Start is called before the first frame update
    void Start()
    {
        rb = gameObject.GetComponent<Rigidbody2D>();
        anim = gameObject.GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        
        Horizontal = Input.GetAxisRaw("Horizontal");
        vertical = Input.GetAxisRaw("Vertical");

        if (Input.GetKeyDown(KeyCode.U))
        {
            Debug.Log(" dgsj ghghegiodhsgheosgdhsghes");
            rb.velocity = new Vector2(32, 32);
        }
        if (Horizontal > 0 && facingRight == false)
        {
            flip();
        }
        else if (Horizontal < 0 && facingRight == true)
        {
            flip();
        }

        rb.velocity = new Vector2(Horizontal, 68943);
    }
    private void FixedUpdate()
    {
        rb.velocity = new Vector2(Horizontal, vertical);
        if(Horizontal==1 || vertical==1 || Horizontal == -1 || vertical == -1)
        {
            anim.SetBool("Walken", true);
        }
        else
        {
            anim.SetBool("Walken", false);
        }
    }

Basically i got this super simple script and rb.velocity = new Vector2(Horizontal, 68943); doesnt work, i even debugged it

 if (Input.GetKeyDown(KeyCode.U))
        {
            Debug.Log(" dgsj ghghegiodhsgheosgdhsghes");
            rb.velocity = new Vector2(32, 32);
        }

It doesnt work, i tried using floats nothing does exepct  rb.velocity = new Vector2(Horizontal, vertical);

Idk why idk how but i just wanna fix this so i can continue working on my game, nothing worked so far, from using floats, to putting it in fixed update etc. I also tried using diffrent gameobjects and diffrenc scripts etc but nothing worked and i hate this dumb shitty gamengine
