On my little notebook laptop (Ryzen 7 4700U with Radeon Graphics) using 19.5.303 Py3.9 I don't get this at all.
My assumption is that it's Nvidia driver-related, or OpenCL-related, as the only reliable repro I can get is using Vellum.
Repro:
-OBJ level > Tab > Sphere (Create)
-Hair Utils shelf > Create Guides
-Hair Utils shelf > Simulate Guides
-Hit Play
-Crash
Driver info and OpenCL info below:

Does anything here stand out as non-compatible? is NVIDIA 526.47 potentially too new?
