Why Large-Scale Model Scenes Cause Real Device Crashes

Is there any limitation in Vision Pro when loading scenes with large-scale models?

​Test Case:

Asset: Composite USDA file containing ​10 individual models​ (total triangles count: ~4.2M)

Simulator: Loads and renders correctly

Real Device: Loads asset successfully but ​ failure during rendering phase:

Environment abruptly dims

System spontaneously reboots

How can we resolve this issue? Below are excerpted logs preceding the crash:
