InvalidKeyException thrown when using Addressables.LoadAssetsAsync<T> to load sub-type objects

Package: Addressables


Reproduction steps:
1. Open the attached project “AddressablesBatchLoadBug”
2. Enter Play mode

Expected result: There are no errors in the Console
Actual result: UnityEngine.AddressableAssets.InvalidKeyException is thrown

Reproducible with: 1.20.5 (2020.3.46f1, 2021.3.20f1), 1.21.8 (2022.2.10f1, 2023.1.0b7, 2023.2.0a5)

Reproducible on: macOS 12.4 (Intel), macOS 13.2.1 (M1) (user’s)

Workaround: use LoadResourceLocations first, then call Addressables.LoadAssetAsync<Base>() on each individual location

Full error:
UnityEngine.AddressableAssets.InvalidKeyException: Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown. No Asset found with for Key=Base. Key exists as multiple Types=SO.Sub1, SO.Sub2, which is not assignable from the requested Type=SO.Base
