This looks like something is really broken in your environment. Somehow unix domain sockets do not seem to work. Could you provide some more information about your OS environment (Linux version, architecture, ...) and the steps to reproduce the issue?

same on WSL.

Ah, you're using WSL. This suspiciously looks like https://github.com/microsoft/WSL/issues/3935. Which WSL version are you using? It looks like you need to use WSL 2 for full Python compatibility.
