c# – Resetting inputs while still pressing down keys in Unity3D?

I have a character controller with no rigidbody or collider, and I’m trying to reset my input keys (old input system) when a certain condition turns true. For example if I am running while simultaneously holding down the jump key so W and Space and then a specific condition turns true, despite still holding down W and Space, they will “reset” and my player will stop moving until I release and then press those keys again. Or if I’m pressing W on its own, or Space on its own.

I made a very simple controller script to use to test this, and I’ve tried wrapping a bool around the code called isMoving and then if another bool such as isSliding turns true, then isMoving turns false which would prevent movement, but with how I did it, no keys reset. I also tried to use a Raycast that casted forward which would also turn isMoving false if it hit a specific collider, but I could still hold down those input keys and perform the same action.

void Update()
{
    isGrounded = controller.isGrounded;
    if (isGrounded)
    {       
        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        float playerSpeed = Input.GetKey(KeyCode.LeftShift) ? sprintingSpeed : walkingSpeed;

        Vector3 forward = transform.forward * z;
        Vector3 right = transform.right * x;

        move = (forward + right).normalized * playerSpeed;

        if (Input.GetButtonDown("Jump"))
        {
            move.y = Mathf.Sqrt(jumpHeight * -2f * gravity);
        }
    }

    move.y += gravity * Time.deltaTime;
    controller.Move(move * Time.deltaTime);
}
