What's Wrong?

In Claude Code’s agents view, keyboard input becomes unresponsive after entering a background session and then returning to the session list.

After this happens:

• Arrow keys do not move the selection.
• Esc does not work.
• Other keystrokes appear to be ignored.
• There is no visible cursor movement or UI response.
• The only reliable recovery is to close the terminal window.

This happens consistently on my Windows setup.

What Should Happen?

After returning to the agents/session list, keyboard input should continue to work normally.

For example:

• Arrow keys should move the cursor or selection.
• Esc should exit or go back.
• q or other supported keys should work as expected.

Environment:

• Claude Code version: 2.1.143
