Crash in LightProbesManager::GetLightProbesJobDataFromStaged after exiting Play mode with additive scenes baked in auto-mode



Steps to repro:
1. Open the attached project and "SimpleOutdoorsA" scene;
2. Drag and drop scene "additive" from the Project view to Hierarchy;
3. In the Lighting window (Window>Rendering>Lighting) enable Auto Generate checkbox;
4. Wait until scene's lighting is baked;
5. Once the scene's lighting is baked, enter Play mode;
6. Exit Play mode.

Actual result:
Editor crashes. See attached video.

Expected result:
Editor doesn't crash after exiting Play mode.
Regression introduced in Version 2022.2.

Workaround is to generate lighting manually without using auto-mode.

- After further reopening of the repro project following the crash, a memory allocator error is shown, preventing an Editor launch;
- Reproducible in Version 2022.2.0a14;
- Not reproducible in Version 2022.1.1f1, 2021.3.3f1;
- Reproducible on Windows;
- Reproducible with either GPU PLM or Enlighten set as the baking backend;
- The issue is specific to the project.
