[BUG] Raw <invoke> XML printed to terminal and session hangs — requires user message to resume (Windows, v2.1.168)

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?

During normal operation, Claude outputs raw <invoke> XML for tool calls directly to the terminal, then the session halts indefinitely. Pressing Enter has no effect. The only way to resume is to send a new message (e.g. "continue").

This occurs from the very beginning of any session — not only after long sessions. It has been happening consistently for several days with no changes on the user side.

The word "count" appears in the terminal immediately before the XML every time.

What Should Happen?

Claude Code should silently intercept the <invoke> XML, execute the tool, return the result to the model, and continue processing — without printing raw XML to the terminal and without requiring any user input to resume.

Steps to Reproduce

1. Open Claude Code in PowerShell on Windows 11 (any directory — confirmed

to occur in both regular directories and Git worktree directories)

1. Ask Claude to perform a task that involves multiple tool calls

(e.g. "Read this file and search for a pattern")

1. Observe that Claude prints "count" followed by raw <invoke> XML to the

terminal, then stops

1. Press Enter — no response
2. Type any message (e.g. "continue") and press Enter — Claude resumes

from exactly where it left off

Additional Information

• Restarting Claude Code does not resolve the issue
• Also reported via /bug command (Feedback ID: d541bad9-145a-48c7-831f-71b55ec4e4a4)
• Related to (but distinct from) issue #62344: occurs from session start

rather than only in long sessions, and recovers with a user message
rather than requiring /clear
