Runtime Navmesh not working on mobile build

I am using the Unity Navmesh Components system for the movement of a group of characters. The system is working perfectly in the editor but the characters are not moving in the iOS build. I can't seem to find any other posts regarding this issue.

I am not sure if the code is relevant to the issue since it is working fine in the editor, but here it is for reference.

 public void MoveToPosition(Vector3 position)
     {
         if(runningCoroutine != null)
         {
             StopCoroutine(runningCoroutine);
             runningCoroutine = null;
         }
         else
         {
             runningCoroutine = StartCoroutine(moveToPosition(position));
         }
     }
 
     IEnumerator moveToPosition(Vector3 position)
     {
         SetWalking(true);
         SetNavMovement(position);
 
         float time = 0.0f;
         Vector3 startPos = _transform.position;
         while (!_navAgent.isStopped)
         {
             if ((_transform.position - startPos).magnitude > 1.0f)
             {
                 startPos = _transform.position;
                 time = 0.0f;
                 yield return null;
             }
             else
             {
                 time += Time.deltaTime;
                 if(time > 2.0f)
                 {
                     _navAgent.isStopped = true;
                 }
                 yield return null;
             }
         }
 
         SetWalking(false);
     }
 
     private void SetWalking(bool value)
     {
         isMoving = value;
         _animator.SetBool("isWalking", value);
     }
 
     private void SetNavMovement(Vector3 position)
     {
             _navAgent.isStopped = false;
             _navAgent.destination = position;
     }

I've been looking for a fix for a couple of days now and I would really appreciate some help. Thanks in advance.
