Codex desktop stopped showing local threads after update, but ~/.codex data is still present

I hit a similar issue after using Settings > General > Import other agent setup. Local session files exist but the app’s sidebar, search, and project mapping are broken. Posted a full writeup titled: “Codex macOS: “Import other agent setup” corrupted sidebar, chat titles, timestamps, and project mapping” Mine happened today and it’s interesting that yours happened a month ago.
