Why is Unity Addressables not working when I build to Windows or Android?

I have recently switched my Unity project to use the Addressables system to improve asset load speed. Everything works perfectly when I run in Unity playmode, however ONLY when I go to build to Windows or Android (it builds as "successful") but it appears the asset keys just fail to load when running in the build.

*I am using Unity Beta 2021.0.1.0b2 but have tried on the earlier releases. *My asset is marked as "Addressable" and the addressable is named correctly. *I "Default Build Script" before I deploy. *I have tried multiple times even reinstalling Unity and built to both Windows and Android. *Addressable settings have been "Pack together" and "Pack Separately".

Here is a simplified version of the script (with the exact same error)... that just loads and instantiates an Addressable-marked gameobject (with a UI image attached) from my asset folder onto the canvas when a button is clicked. As per above, this works perfectly in Unity playmode, but fails when I build.

What am I doing wrong? I have been stuck on this for some time now and would really appreciate any help....!

[SerializeField] ButtonTest bttn;  [SerializeField] Transform spawnPos;    private void Awake()  {      this.transform.Find("Bttn").GetComponent<Button>().onClick.AddListener(() => LoadPicture());      spawnPos = this.transform.Find("SpawnPos");  }    private void LoadPicture()  {      Addressables.LoadAssetAsync<GameObject>("Drink").Completed += drink =>      {          if(drink.Status == AsyncOperationStatus.Succeeded)          {              GameObject go = drink.Result;              GameObject g = Instantiate(go, transform.position, transform.rotation);              g.transform.SetParent(spawnPos, false);          }          else          {              Debug.Log("Load Failed");          }      };  }
