NavMeshAgent does not move to an updated position

Hi
I've got the following script asking a navMeshAgent to move to a position dynamically. What's happening is the Agent moves to the starting location of the Player gameObject and doesn't move or rotate after that, even though the player object has moved.

   public class EnemyMover : MonoBehaviour
     {
     
         public GameObject bullet;
         public NavMeshAgent agent;
         public Transform target;
         public float fireRate;
         private float nextFire;
         public GameObject Player;
         public float fireRange;
         Vector3 LastKnownPos;
         int takeDamage;
         public int EnemyDamage;
         public int HP;
         public Transform shotSpawn1;
         public Transform shotSpawn2;
         Transform shotActive;
         public Transform eye;
         public float range;
         public LayerMask playerLayer;
     
     
         // Start is called before the first frame update
         void Start()
         {
             fireRange = 6f;
             takeDamage = 2;
             HP = 6;
             shotActive = shotSpawn1;
     
         }
     
         void Update()
         {
             //Debug.DrawRay(eye.transform.position, transform.TransformDirection(Vector3.forward)*range);
             //RaycastHit sight;
             //if (Physics.Raycast(eye.transform.position, transform.TransformDirection(Vector3.forward), out sight, range, playerLayer))
             //{ 
                 CustomEvent.Trigger(gameObject, "alert"); 
                 agent.updateRotation = true;
                 agent.SetDestination(Player.transform.position);
                 agent.stoppingDistance = fireRange;
                 //Vector3 lastKnownPos = Player.transform.position;
             
            // }
         }
