Error : Command 'openmc' returned non-zero exit status 255

Dear all,

Does anyone know what happened with this and what should i do?
for settings.batches = 50
settings.inactive = 10
settings.particles = 10000

Thx,
Auliyah

How did you install openmc, @Auliyah11?

Can you show me the output of h5cc -showconfig command?

I would try restarting your Jupyter kernel and then rerunning.
