What issue are you seeing?

I cannot archive a conversation reliably in the Codex App for Windows.

When I archive a conversation, it briefly disappears from the sidebar and then reappears. If I open the conversation again, I can no longer continue it because sending a new message fails.

Restarting the Codex App restores the ability to send new messages in that conversation, but the archiving problem remains.

The UI does not show a clear error explaining what went wrong.
