Bug Addressables.LoadSceneAsync Breaks with Domain Reloading Disabled

When I try to load a scene via the addressables system it loads correctly the first time, but when I run play mode again it will not load (stuck at 0 percent), until I force a domain reload by editing script or something.

Maybe not relevant but when I try to activate the unloaded scene I get this error:

NullReferenceException: Object reference not set to an instance of an object
UnityEngine.ResourceManagement.ResourceProviders.SceneInstance.Activate () (at Library/PackageCache/com.unity.addressables@1.1.10/Runtime/ResourceManager/ResourceProviders/ISceneProvider.cs:27)

Saw someone else was having the same problem a few months back here (he has provided code), but did not see a response or solve:
https://forum.unity.com/threads/addressables-are-here.536304/page-9#post-5398932

Edit: This only happens when the activateOnLoad parameter is false. I am using LoadSceneMode.Single. Manually activating the scene after load does not prevent this bug.

 

I tried this on 1.1.10 and 1.83, same problem with both

Edit: Found out that calling Addressables.InitializeAsync() before using the system prevents the issue from happening.

 

Looks like Addressables.InitializeAsync() doesn't band-aid issues with Domain Reloading off and Addressables.InstantiateAsync() - on non-reloaded re-launch I am getting missing reference exceptions when operating on the result of the complete callback of AsyncOperationHandle

UnityEngine.MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.

 

I have the same problem as OP. I am on Unity 2020.2.0f1, Addressables: 1.16.15
