Trouble Installing openmc with mamba and miniforge

Greetings, I have been trying to install openmc and getting it to work but to no avail, I have been following the guide on the oficial website. Installation with mamba and conda-forge .
I have followed the steps until I get the environment with openmc, but when I try to check the version I get an error and googling does not seem to yield results.
