Reproduction steps:
1. Open the attached “repro_IN-95885“ project
2. Open the “Assets/Scenes/OmegaProject.unity“ Scene
3. Make sure that the “Graphics API for Windows“ (“Edit → Project Settings… → Player → Other Settings“) is set as “Direct3D12“
4. Enter the Play Mode
5. Observe the crash

Reproducible with: 6000.0.42f1, 6000.1.0b10, 6000.2.0a6
Couldn’t test with: 2022.3.60f1 - A lot of missing namespaces due to "Core RP Library" downgrade

Reproducible on: Windows 10 (22H2), Windows 11 (23H2) (user’s)
Not reproducible on: No other environments tested

Note: Crash is not 100% consistent, so if the Editor doesn’t crash after entering the Play Mode - exit the Play Mode and repeat the steps
