This issue was automatically created by Sentry via [Explorer Alpha Github Issue Creation](https://sentry.io/organizations/decentraland/monitors/alerts/3130340/)

Start at FlowInternalAsync in Assets/DCL/Infrastructure/SceneLifeCycle/SceneDefinition/Systems/LoadSceneDefinitionListSystem.cs:128 and trace the async path through AssetsLoadingUtility.cs, RetrieveSceneFromVolatileWorld.cs, AssetPromiseAsyncExtensions.cs, and TeleportController.cs. Identify where the continuation is registered more than once or status is accessed after awaiting. Done means the reported InvalidOperationException no longer occurs during the affected scene-loading or teleport flow.
