You didn’t do anything wrong. I get the same error in a new temporary environment.

There seems to be a problem with one of GeoIO’s dependencies. I tracked the issue down to here. You will want to follow that issue for a fix. The current workaround seems to be to add snappy_jll@1.1.10 to your environment.
