I did a simple hourglass render that worked fine. I tried adding a sand simulation using a particle instance modifier and geometry nodes. Blender crashes any time I try to render with Octane or activate the render preview mode.

Here is the .blend file, you will need to run the simulation again if needed.

The issue seems related to Geometry nodes. We'll look into that.
Meanwhile, my advice would be to use the Octane Scatter node to instance sand grains on the particles.
Thanks for your report and scene!
