Silent crash when raycasting on a specific dense mesh

PhysX

-

How to reproduce:
1. Open the “DebugRay.zip“ project
2. Open the “OutdoorsScene”
3. Enter Play Mode
4. Hover over the long mesh in the Game view
5. Observe the Editor

Expected result: The Editor continues to function
Actual result: The Editor freezes and silently crashes after some time

Reproducible in: 2021.3.53f1, 2022.3.64f1, 6000.0.52f1, 6000.1.10f1, 6000.2.0b9, 6000.3.0a1

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- The object was exported from a CAD file through Pixyz, and it has many triangles, which might be part of the reason for the crash
- It looks like the crash is caused by a stack overflow

    I notice the crash doesn't happen if you disable the 'Use Fast Midphase' cooking option. It's a workaround for now.
