Unity C# Object Reference

Question

What I'm trying to do is enabling the fist objects when I click trigger and disable the hand objects on my VR controllers and then when I release them, disable the fist objects and enable the hand objects. I get the error object reference not set an instance of an object. I thought initially it was a problem with my formatting but at this point I am confused, it seems like I have everything referenced IDK :/ :

using System.Collections;
using System.Collections.Generic;
using System.IO.MemoryMappedFiles;
using UnityEditor;
using UnityEngine;
using UnityEngine.XR;

public class Hand : MonoBehaviour
{
    private InputDevice targetDevice;
    // Start is called before the first frame update
    void Start()
    {
        GameObject.Find("RightFist").SetActive(false);
        GameObject.Find("LeftFist").SetActive(false);

        List<InputDevice> devices = new List<InputDevice>();
        InputDeviceCharacteristics rightControllerCharacteristics = InputDeviceCharacteristics.Right | InputDeviceCharacteristics.Controller;
        InputDevices.GetDevicesWithCharacteristics(rightControllerCharacteristics, devices);

        foreach (var item in devices)
        {
            Debug.Log(item.name + item.characteristics);
        }

        if (devices.Count > 0)
        {
            targetDevice = devices[0];
        }
    }

    // Update is called once per frame
    void Update()
    {
        targetDevice.TryGetFeatureValue(CommonUsages.trigger, out float triggerValue);
        if (triggerValue > 0.1f)
        {
            EnableFists();
            DisableHands();
        }
        else
        {
            EnableHands();
            DisableFists();
        }

    }

    private static void EnableFists()
    {
        GameObject.Find("RightFist").SetActive(true);
        GameObject.Find("LeftFist").SetActive(true);
    }
    private static void DisableFists()
    {
        GameObject.Find("RightFist").SetActive(false);
        GameObject.Find("LeftFist").SetActive(false);
    }
    private static void EnableHands()
    {
        GameObject.Find("RightHand").SetActive(true);
        GameObject.Find("LeftHand").SetActive(true);
    }
    private static void DisableHands()
    {
        GameObject.Find("RightHand").SetActive(false);
        GameObject.Find("LeftHand").SetActive(false);
    }
}
