Rotating a direction Vector3 by Quaternion

I've done research but every solution I've found gives me the same result when trying to just move forward in relation to the camera. C#

 [RequireComponent(typeof(Rigidbody))]
 public class RollerController : MonoBehaviour {
     public float BasicSpeed = 2f;
     public float BoostAmount = 10f;
     CameraController playerCamera;
     // Use this for initialization
     void Start () {
         playerCamera = GetComponent<CameraController>();
     }
     
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKey(KeyCode.W))
             rigidbody.AddForce((camera.transform.rotation * playerCamera.transform.forward) * BasicSpeed);
 
         
     }

this code seems like it should work right? My game object just moves in circles when I hold the w key down.. What is going on?!?

edit:: sorry been long day it actually just doesn't rotate at and continues along the forward direction?

edit:: Thought maybe my camera controller was messing with the rotation of the camera when passing the values?? just a thought here's the camera controller I am using. Its not complete was just getting it working first.

 public class CameraController : MonoBehaviour {
     public Transform CameraTransform;
 
     public float DistanceUp = 10;
     public float DistanceBack = 5;
     public float RotationSpeed = 3;
 
     public float total = 0;
     // Use this for initialization
     void Start()
     {
 
     }
     
     // Update is called once per frame
     void Update()
     {
         total += Input.GetAxis("Mouse X") * RotationSpeed;
         CameraTransform.rotation = Quaternion.Euler(new Vector3(40, 0, 13));
         CameraTransform.position = transform.position + new Vector3(0, DistanceUp, -DistanceBack);
         CameraTransform.RotateAround(transform.position, Vector3.up, total);
     }
 }
