        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Speed", movement.magnitude);
    }

    private void FixedUpdate()
    {
        rb.MovePosition(rb.position = movement * movespeed * Time.fixedDeltaTime);
    }
}

That is not the correct thing to do. Maybe you want this

rb.MovePosition(rb.position + movement * movespeed * Time.fixedDeltaTime);

Another way is to use rb.AddForce()
