I cannot reproduce this issue on Linux nor macOS. Are you using the latest Miniforge3 and is your base environment (mamba update -n base --all) up to date? Do you have any channel configuration set in your ~/.condarc?

Miniconda is not Miniforge3. Or was that a typo? It would explain the problems you experience because Miniconda uses the repositories provided by Anaconda instead of the conda-forge community repository. Unfortunately, due to licensing issues, we cannot use the Anaconda channels and thus cannot offer any support. But you can try to enable the conda-forge repository for the installation of pyarts. It might work:

mamba create --name pyarts --override-channels -c conda-forge -c rttools pyarts
