Windows crashes on enabling Particle Renderer

[sgpearse]

With our current Windows installer, create and enable a Particle Renderer. Vapor will crash.

@StasJ - I haven't been able to debug this on Windows, but by chance I've been able to reproduce a crash happening nondeterministically on macOS x86 and appleSilicon. I suspect it's the same issue as what's happening on Windows.

Here's the trace from lldb. It looks like it's coming from the recent refactorization in #3541, at ParticleRenderer.cpp:421.

To reproduce, enable the particle renderer in the attached session/data file. This causes the crash for me 1/10th of the time.

Hey @sgpearse, thanks for adding the session and data files. I am unable to trigger the bug after trying >100 times across three computers (two M1 and an x86).

I'm also getting a crash every time on Windows
