    I have this issue as well after upgrading from 2020.3.17 to 2020.3.26. In my testing it has nothing to do with labels. The error happens when trying to load a ScriptableObject which has a field that is an instance of a custom serializable type. So if you, say, declare some serializable struct and have a field of that type in your ScriptableObject, you will get this error.

    Still not fixed with Unity 2021.2.8f1 and Addressables 1.19.17. Had to downgrade to 1.17.17.

    System.Exception: Unable to load asset of type UnityEngine.GameObject from location Assets/Core Assets/Graphics/ParticleEffects/KriptoFX/Pack4/Effect24_GroundCrack.prefab.
    UnityEngine.ResourceManagement.Util.DelayedActionManager:LateUpdate () (at Library/PackageCache/com.unity.addressables@1.19.17/Runtime/ResourceManager/Util/DelayedActionManager.cs:159)

    I also have the same error with 2020.3.25f1 after upgrading from 2020.3.22f1. If I downgrade the exceptions go away. Happens with Addressables 1.19.3 and 1.19.5. If I use Addressables 1.18.19 then I get completely different exceptions (but the exception is always in DelayedActionManager LateUpdate method (line 159).

    I have the same error and I don't that it's the same issue or not.
    Error is reproducible with Unity 2020.3.24f1 and 2020.3.25f1
    Not reproducible with 2020.3.23f1
    Addressables package is 1.19.14
    So the issue is in engine side.
    In my case Addressables.LoadResourceLocationsAsync(label) method returns more locations than need. After debugging i found out the issue is in ContentBuildInterface.GetTypeForObjects(ids) method in GatherSubObjectTypes(ObjectIdentifier[] ids, string guid) in AddressableAssetEntry class
