version 0.4.1 not working: Fails many checks at start up and continually gives error: "cannot add network services: listen tcp 127.0.0.1:2222: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted."

You can resolve this issue yourself with version 0.3.7 but it would be good if it also worked on the new version

I'm on Windows 11 running WSL 2.

The following console output is given:
