Nav Mesh Problem with SetDestination

Why does t$$anonymous$$s work t$$anonymous$$s pops up

 public float deathDistance = 0.5f;
 public float distanceAway;
 public Transform t$$anonymous$$sObject;
 public Transform target;
 private NavMeshAgent navComponent;

 void Start() 
 {
     target = GameObject.FindGameObjectWithTag("Player").transform;
     navComponent = t$$anonymous$$s.gameObject.GetComponent<NavMeshAgent>();
 }

 void Update() 
 {

     float dist = Vector3.Distance(target.position, transform.position);

     if(target)
     {
         navComponent.SetDestination(target.position);
     }

     else
     {
         if(target == null)
         {
             target = t$$anonymous$$s.gameObject.GetComponent<Transform>();
         }
         else
         {
             target = GameObject.FindGameObjectWithTag("Player").transform;
         }
     }
     if (dist <= deathDistance)
     {
         //KILL PLAYER
     }
 }
