Editor crashes when loading a scene from a runtime-updated Addressables catalog

Package: Addressables


How to reproduce:
1. Open the user's attached project ""
2. In the Project window go to Assets/Scenes/Test.unity
3. Enter Play mode
4. Observe the blue cube in the Game view
5. Go to the project's "" folder and copy (overwrite) all files from "ServerData-Updated\red" to "ServerData\StandaloneWindows64"
6. Go back to Unity Editor
7. In the Game view click "Check and Reload"

Expected result: The scene updates and a red cube appears
Actual result: Editor crash

Reproducible with: 1.16.10 (2019.4.22f1), 1.16.16, 1.17.5-preview (2020.2.7f1, 2020.3.1f1, 2021.1.0b12, 2021.2.0a9)
Could not test with: 2018.4.32f1 (Due to Addressables script errors)

-The copying of the files from "ServerData-Updated\red" to "ServerData\StandaloneWindows64" is needed for simulating runtime Addressable update
-When opening the project after the crash, the red cube appears(Expected result)
-The crash would occur as well if the files will be copied from "ServerData-Updated\blue" to "ServerData\StandaloneWindows64"
-Copying the files from "ServerData\StandaloneWindows64" to "ServerData-Updated\red" or "ServerData-Updated\blue" will not result in a crash

  1. Resolution Note:

    Fixed in 2021.2.0a17
    The user must unload the scene (Addressables.UnloadSceneAsync) first before updating the catalog and reloading the scene.
