From the Game view and Hierarchy it looks like the unload happens, however each time this happens I’m seeing leaks in the Addressable Profiler:

An experiment I’ve done: if in ChainOperation.cs one adds this line to the start of Destroy(): if(m_WrappedOp.IsValid()) the exception doesn’t happen however the UnloadSceneOps still get leaked.

Thanks for the report! Which version of Addressables are you using? Could you also file a bug report for us? Unity QA: Building quality with passion
