What's Wrong?

When using the /config slash command in Claude Code, invoking it a second consecutive time within the same session causes the entire terminal to become
completely unresponsive. No input is accepted after this point — the session is effectively frozen and must be force-terminated by closing the terminal
window or killing the process externally.

This only occurs on the second (or subsequent) invocation of /config. The first call works normally. There is no error message, no timeout, and no way to
recover without restarting the session.

What Should Happen?

The /config command should open the configuration interface successfully on every invocation, regardless of how many times it has been used in the current
session. After closing the config menu, it should be possible to invoke /config again without any side effects or degraded behavior.
