Try using [mamba](https://mamba.readthedocs.io/en/latest/) instead of conda for the installation. See this [discussion](https://discourse.pangeo.io/t/mamba-mature-enough/3154) on the Pangeo discourse forum.

Your environment will need to have python 3.9 installed but you currently have 3.10.

`mamba install python=3.9`
