What's Wrong?

Bug Description

Claude Code Desktop app (Windows) does not respond when using local sessions. Messages are sent successfully (session titles are auto-generated), but no reply is ever returned from Claude.

Environment

• OS: Windows (C:\Users\PB0733User)
• Claude Code Desktop version: v2.1.74
• Claude Code CLI version: v2.1.74
• Node.js: v24.14.0
• Git: v2.53.0.windows.1
• Plan: Claude Pro

Steps to Reproduce

1. Open Claude Code Desktop app
2. Create a new session
3. Confirm environment is set to "Local" (shown in bottom right)
4. Send any message (e.g. "Create a simple hello world Python script")
5. Session title is auto-generated, but no response is returned

Expected Behavior
Claude should respond to the message in the local session.

Actual Behavior
No response is returned. The input field resets, the session title is auto-generated from the message, but the chat area remains completely empty.

Additional Notes

• CLI version (claude in terminal) works perfectly fine
• Remote/Web sessions show a "Continue with" popup instead of responding locally
• Reinstalling the app did not resolve the issue
• Re-login via /login was performed and authentication is confirmed
• The bottom bar shows "編集を自動承認" (Auto-approve edits) when Local mode is active, suggesting local mode is recognized, but still no response

What Should Happen?

Claude should respond to messages sent in local sessions within the Desktop app, the same way it responds in the CLI (terminal) version.
