I followed the Windows instructions (https://github.com/astronomer/astro-cli) and tried astro 0.13.1, 0.19.0 and 0.20.0, all with the same issues.
I get the docker containers running and I can connect to the airflow web page.
The example-dag does not show up, and any plugin or dag in the folders get the same error on the web server logs: OSError: [Errno 38] Function not implemented
