Physics Character Controller problem

Hello, I am relatively new to unity and I have made a physics based character controller using rb.MovePosition. When I go left, it works, but when I go right, it doesn’t move. There are no compiler errors and the rest of the game runs normally. Can someone help? Here is my code:

void Update()
    {
    rb.MovePosition(transform.position + input * Time.deltaTime);
    if (Input.GetButtonDown("Left"))
    {
	input = new Vector3((Input.GetAxis("Horizontal") - 10) , 0, (Input.GetAxis("Vertical")));    
    }
    
    if (Input.GetButtonDown("Right"))
    {
	input = new Vector3((Input.GetAxis("Horizontal") + 10) , 0, (Input.GetAxis("Vertical")));    
    }
	
    if (!Input.GetButtonDown("Left") && Input.GetButtonDown("Right"))
    {
	input = new Vector3(0, 0, 0);    
    }

If there are any optimisations I could do to this code, let me know.,Hello, I am relatively new to unity, and i have created a physics based character controller using rb.MovePosition.

If there are any optimizations I could do to this code, you can let me know too.

I think the error happens from third if statement.
(!Input.GetButtonDown("Left") means you are not pressed left button & Input.GetButtonDown("Right") pressing right button generally you only pressed right button, right? then code runs to position 0. Hope you can remove that code block & check again.
