So how do I rotate my camera to my player

Question

So every time I want to right click, I want to move my camera to where my mouse is, and rotate my player to my camera. But instead when I right click my camera just go crazy like a madlad. my camera is a isometric btw.

Here my code yall madlads. public CharacterController controller;

     public float speed = 12f;
     public float gravity = -9.18f;
     
 
     public Transform groundCheck;
     public float groundDistance = 0.4f;
     public LayerMask groundMask;
 
     Vector3 velocity;
     bool isGrounded;
     public Transform maincamera;
     void Update()
     {
         transform.LookAt(maincamera);
         transform.LookAt(maincamera, Vector3.left);
     }
     
        
 
     float AngleBetweenTwoPoints(Vector3 a, Vector3 b)
     {
         return Mathf.Atan2(a.y - b.y, a.x - b.x) * Mathf.Rad2Deg;
         isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
 
         if (isGrounded && velocity.y < 0)
         {
             velocity.y = -2f;
         }
 
         if (Input.GetKey("left shift") && isGrounded)
         {
             speed = 20f;
         }
         else
         {
             speed = 12f;
         }
 
         float x = Input.GetAxis("Horizontal");
         float z = Input.GetAxis("Vertical");
 
         Vector3 move = transform.right * x + transform.forward * z;
 
         controller.Move(move * speed * Time.deltaTime);
 
        
 
         velocity.y += gravity * Time.deltaTime;
 
         controller.Move(velocity * Time.deltaTime);
     }
 }
 public class cameraSystem : MonoBehaviour
 {
     public Camera cam;
     public float speed = 5.0f;
     Vector2 movement;
     Vector2 mousePos;
     void Update()
     {
         if (Input.GetMouseButtonDown(1))
         {
             Debug.Log("Aiming");
             transform.position = new Vector3(speed * Time.deltaTime, 0, 0);
             // If the right button on the mouse is hold down or click it moves the camera to it position.
 
         }
     }
 }

 // Have "player" as a variable of type gameobject and assign in inspector
 Vector3 playerPosition = player.transform.position;
 
 // This class is assigned to the camera object
 Vector3 cameraPosition = transform.position;
 
 Vector3 dirBetween = (playerPosition - cameraPosition).normalized;
 
 // Rotate camera to look at player
 transform.forward = dirBetween;
 
 // To rotate player to look at camera: player.transform.forward = -dirBetween;
