[Bug] /config command hangs on second invocation

Bug Description
/config hangs the second time we open it

Reproduce

1. Start claude CLI
2. /config
3. escape twice to exit out
4. /config

It shows the config screen but it's frozen. Typing in the search box, pressing escape, etc, nothing happens. I have to control-C kill claude.
