Impossible to visualize the geometry on the example of the pin cell reactor in the documentation.[RuntimeError: OpenMC aborted unexpectedly] (macOS/conda)

Hello,

I’m just getting started with OpenMC, so I’m starting by discovering the first examples in the documentation, in particular the pin-cell reactor. However, when I get to the geometry visualization stage, I’m not sure what to do. However, when I compile I get the following error message: RuntimeError: OpenMC aborted unexpectedly.

So I tried the other method proposed in a previous discussion (:Discussion ) but I get the same error message.

Has anyone encountered this problem before and could they help me? I downloaded OpenMC on my mac with Conda/Mamba.

I know the subject seems to have already been covered in this discussion: https://openmc.discourse.group/t/runtimeerror-when-plotting-in-pincell-tutorials-universe-plot-and-openmc-plot-geometry/2605
However, I don’t understand the solution.
