Help with some code (mouse directional targeting)

Unity Engine

SO im trying to have a target follow a mouse around my player
Similar to this:

i even tried to copy his code, my issue is i cannot get the target to rotate around the player, its sorta stuck rotating somewhere else and then when i move my player the target starts to move across the screen really fast.

my code:

    private float Radius = .24f;
    private float angle;
    private Vector3 v3pos;
   
    void FixedUpdate () {
        GameObject player = GameObject.Find("Player1");
       
        v3pos = Input.mousePosition;
        v3pos.z = (player.transform.position.z - Camera.main.transform.position.z);
        v3pos = Camera.main.ScreenToWorldPoint(v3pos);
        v3pos = v3pos - player.transform.position;

        angle = Mathf.Atan2(v3pos.y, v3pos.x) * Mathf.Rad2Deg;

        if (angle < 0.0f) angle += 360.0f;
        transform.localEulerAngles = new Vector3(0,0, angle);

        float xpos = Mathf.Cos(Mathf.Deg2Rad * angle) * Radius;
        float ypos = Mathf.Sin(Mathf.Deg2Rad * angle) * Radius;

        transform.localPosition = new Vector3(player.transform.position.x + xpos * 2, player.transform.position.y + ypos * 2, 0);

    }

I figured it out just now, it was the final tranform.localposition i changed it to transform.position and now it works.

EDIT: well it sorta works, it ever so slightly moves the target a little off while my character is moving, its barely noticeable tho.
