[BUG] Code tab shows no response to messages — Chat tab works fine on Windows

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

In the Code tab of Claude Desktop, I type a message and it shows up but there is no response and no loading indicator. This happens in every new session. The Chat tab works perfectly fine.

What I tried:

• Full clean reinstall (removed AppX package, deleted all leftover Claude folders, reinstalled as Administrator)
• Signed out and back in
• Tried multiple new sessions

Environment:

• Windows
• Latest version of Claude Desktop (just installed today)

What Should Happen?

After typing a message in the Code tab, Claude should respond normally just like it does in the Chat tab.

This is a recent regression. Claude Code was working in the Desktop app as recently as Thursday April 3rd. It broke sometime between then and now.
