Crash on various stack traces when allocating memory while opening a specific Scene



Reproduction steps:
1. Open the attached “repro_IN-77564“ project
2. Open the “Assets/Scenes/SceneMap2“ Scene
3. Observe a crash

Reproducible with: 2021.3.39f1, 2022.3.33f1
Not reproducible with: 6000.0.6f1

Reproducible on: Windows 10 (22H2)
Not reproducible on: No other environments tested


* If the crash doesn’t reproduce after opening the “SceneMap2“ Scene, try closing the Editor - it should reproduce then
* If the “Could not allocate memory: System out of memory!“ error appears, it won’t go away - delete the project and extract it again from the archive
* Couldn’t find the “Fixed in“ version, as the crash is inconsistent
* Not reproducible in the Player
