AskUserQuestion tool fails silently on Windows 11 — shows 'Answer questions?' instead of interactive prompt

Description

When the agent calls the AskUserQuestion tool, the tool call appears to succeed from the agent side but the user never sees an interactive question prompt. Instead, the text "Answer questions?" is rendered as a static message, and the user has no way to respond.

The agent sees the tool as having been called successfully and continues, never receiving user input. This makes any workflow that depends on structured user questions (like GSD's discuss phase) completely non-functional.

Environment

• OS: Windows 11 Pro 10.0.26200
• Shell: bash (Git Bash)
• Claude Code: latest (CLI)

Steps to Reproduce

1. Start Claude Code on Windows 11
2. Have the agent call AskUserQuestion with any question
3. Observe that "Answer questions?" appears as static text
4. User has no interactive prompt to respond to

Expected Behavior

An interactive prompt should appear allowing the user to select from options or type a response.

Actual Behavior

Static text "Answer questions?" is displayed. No interactive UI. The tool returns without user input. The agent either continues without answers or repeatedly retries the tool call.

Additional Context

This has been observed across multiple sessions. The user reports having encountered this issue before on the same setup. It blocks all structured questioning workflows.
