What's Wrong?

The Claude Code tab in the Mac desktop app is completely unresponsive. I can type messages and press enter but nothing comes back — no response, no loading indicator, nothing. The Chat and Cowork tabs in the same app work perfectly fine. This has persisted through every troubleshooting step listed below.

What Should Happen?

Claude Code should respond to messages the same way Chat does. continue my build.

Error Messages/Logs

1. Open the Claude desktop app on macOS 15.7.3 (Sequoia)
2. Click the Claude Code tab
3. Type any message and press enter
4. Nothing happens — no response ever comes
