Reproduction steps:
1. Open the attached “repro-project“
2. Open the “Assets/Scenes/AssembleBase_always_addressable.unity“ scene
3. Open the Addressables Groups window, and select “Use Existing Build (WebGL)“ in the “Play Mode Script” dropdown menu
4. In the same window, ensure that the Profile selected in the “Profile“ dropdown menu is set to “LP Unity CCD (Staging WebGL)”
5. Enter Play Mode
6. Observe the crash

Reproducible with: 2022.3.21f1, 2023.2.13f1
Could not test with: 2021.3.36f1 (due to errors when downgrading the project), 2023.3.0b10 (due to Addressables failing to load and other errors)

Reproduced on: Windows 10, Windows 11 (by reporter)
Not reproducible on: No other environment tested

Notes:
1. Not reproducible in Player
2. During runtime, you can observe the first Addressable being loaded. Once that loading progress goes past 99.0 and disappears, the Addressable should be finished loading, and get instantiated in the scene, instead, the Editor crashes
