System Information
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3050 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.78

Blender Version
Broken: 3.4, f43c2d9abe0f8b6efca8fa803774a065a6749a88
Worked: unsure but it's a regression for sure

Short description of error
assert hit BLI_assert(elem) when sculpting with dyntopo in debug (lite) build
I've also been getting crash in release build earlier but not very frequently.

Perhaps related {#101502}?

Exact steps for others to reproduce the error

Open default scene
Switch to sculpt mode
Enable Dyntopo
Attempt to sculpt the cube
