Crash in physx::Dy::SolverCoreGeneralPF::solveVParallelAndWriteBack on collisions when Directional Friction Type is used

Physics

-

How to reproduce:
1. Open tester-attached project (Physx_Crash.zip)
2. Open the 'CrashScene' and enter Play Mode
3. Select the 'RampsAndPaddleRingStandPrefab' GameObject
4. In the Inspector window check the 'Triggered' checkbox on the Paddle Ring Emitter script
5. Follow the particles being emitted from the ramp

Expected result: no crash occurs after a few of collisions
Actual result: the Editor crashes when the particles reach the wall on the other side of the arena

Reproducible with: 2019.3.0a9, 2019.3.3f1, 2020.1.0a24
Not reproducible with: 2018.4.17f1, 2019.3.0a8
Could not test with: 2017.4.37f1(project crashes upon launch)

Notes:
One-Directional or Two-Directional Friction Type must be selected in Physics settings in order to reproduce the crash

  1. Resolution Note:

    A rather unique condition that is hopefully gone in the upcoming PhysX 5 release.

    Running into the same issue on Unity 2021.2.8f1.

    Patch friction "solves the issue".
