Getting the following error in the build:

Looks like it can't make it to get the result in time in one frame. If you use the code from examples

var handle = Addressables.LoadAssetAsync<CustomScriptableObject>("key");
var so = handle.Result;

a null reference will be returned. There's no way to wait for async operation to complete except using coroutines and Completed event callback:

Addressables.LoadAssetAsync<CustomScriptableObject>("key").Completed += handle => Debug.Log(handle.Result.name)

Same for Addressables.InstantiateAsync("key")

Addressables really suffer without synchronous methods. For instance if you init a logic inside a static method marked with RuntimeInitializeOnLoadMethodAttribute and you want it to be executed before any Awake(). So you're trying to load assets with addressables there and you can't do that way. When the async operation completed and it's Completed callback invoked, the train is already far ahead of Awakes.

Thus using Addressables possesses the code with Completed lambda callbacks with bunch of closure allocations everywhere if you're not using async approach in your project in general

we've updated the samples to addressables 1.15.1 and it seems to be running fine. If you continue to get errors, please let us know

Addressables 1.16.15, Unity 2020.1.10f1:

SyncAddressables.Instantiate (System.Object key, UnityEngine.Transform parent, System.Boolean instantiateInWorldSpace) (at Assets/SyncAddressables/SyncAddressables.cs:57)
spawner.FixedUpdate () (at Assets/spawner.cs:34)

Hi @truenoob141 thanks for reporting this issue! The SyncAddressables project has been removed from the repository. The main package now supports synchronous loading https://docs.unity3d.com/Packages/[email protected]/manual/SynchronousAddressables.html#synchronous-workflow
