[Android] [iOS] [IL2CPP] Occlusion culling does not work on Android when a scene is loaded with "Addressables.LoadSceneAsync" on a IL2CPP ARM64 build
How to reproduce:
1. Open the “ReproProject.zip“
2. Open the “Boot“ scene
3. Navigate to the “Edit > Project Settings > Player > Other Settings“
4. Set Scripting Backend to IL2CPP
5. Set Target Architecture to ARM64
6. Build and Run for Android
7. Set the “Pos“ and “Rot“ sliders to the left-most position
8. Note the “Cube: “ value
Expected result: The “Cube: “ is 1
Actual result: The “Cube: “ is not equal to 1

I can confirm that the issue also reproduces in a Standalone macOS build using the Mono scripting backend (Unity 6000.0.38f1).

This happens when script filtering, even at the lowest level, is enabled in ILCPP's build mode, and you can try turning it off as a temporary fix

Resolution Note:
The problem described in this ticket is as designed and can be worked around by including a static occlusion geometry object in the main scene of the project that is included in the player scene list.
