Crash after "[Physics.PhysX] Foundation: Invalid registration detected" errors show up when using Physics.BakeMesh

Physics

-

Steps to repro:
1. Open the project attached by the user
2. Enter Play mode
3. Wait a few seconds until "[Physics.PhysX] Foundation: Invalid registration detected" is shown
4. Close Unity Editor

Expected results: Unity Editor is closed
Actual result: "Fatal Error! GetManagerFromContext: pointer to object of manager 'PhysicsManager' is NULL (table index 9)" window is shown and after pressing Quit button, Unity crashes

Reproducible with: 2019.3.0a11, 2019.3.0f3, 2020.1.0a1, 2020.1.0a16
Couldn't test with: 2019.3.0a10 and older Unity versions due to new Mesh API being unavailable on them

Note:
- Physics.BakeMesh is used in multiple background threads

    Bug is still there in 2020.2.0a12

    I reproduce it with 2020.2.0a10.

    For me, the message "[Physics.PhysX] Foundation: Invalid registration detected" first shows up after I QUIT play mode (I think Physics.BakeMesh doesn't like to be interrupted).

    Once it has happened, the message will show up tons of times as soon as play mode is active.

    The only way to get back to normal is to close Unity, which causes the crash described in this bug report.

    So there are actually 3 issues:
    1) the message should just never show up, even when we exit play mode
    2) if for any reason it shows up, it should be safely restored to a working state so we don't need to close Unity
    3) when we close Unity, it should not crash

    Hope this can help!
