Transform.LookAt Seems To Cause Issues

Hi all, I'm making a "following" script for an object to follow the player if they are within range/sight.

 bool canSeePlayer () {
     RaycastHit hit;
     Vector3 rayDirection = player.position - transform.position;
     float distanceToPlayer = Vector3.Distance( player.position, transform.position );
     if(Physics.Raycast( transform.position,  rayDirection, out hit)) {
         if((hit.transform.tag == "Player") && (distanceToPlayer <= rearDetectionThreshold)){
             //Debug.Log("PLAYER GOT TOO CLOSE");    
             return true;
         }
     }
     if(Vector3.Angle(rayDirection, transform.forward) < fieldOfViewRange ) {
         if(Physics.Raycast( transform.position,  rayDirection, out hit)) {
         //Debug.Log (hit.transform.tag + " " + distanceToPlayer.ToString());
             if((hit.transform.tag == "Player") && (distanceToPlayer < frontDetectionThreshold)){
                 //Debug.Log("CAN SEE PLAYER");    
                 return true;
             }
             else {
                 //Debug.Log("CAN'T SEE PLAYER");
                 return false;
             }
         }
     }
     
     return false;
 }
 
 void Update () {
     if( canSeePlayer() ) {
         //Debug.Log ("MOVE WOLF MOVE");
         transform.LookAt(player);
         transform.position = Vector3.MoveTowards(transform.position, player.position, .1f);
     }
 }

Should be pretty self-explanatory what the code does, uses rays and distances to determine if the player is seen or in range by the object the script is attached to (a cube in this case). It works just as intended, except when I use the transform.LookAt(player) line.

What happens then is that all of the sudden it stops being able to see the player after it changes its direction via lookat. So I'm just not sure what's happening. My line where I print the tag the ray is supposed to be hitting, I get untagged. Which is curious, my player character is definitely tagged as "Player" Again, no issues with the detection when I don't have the cube adjust its direction.

I don't know why it would be inconsistent.
