[BUG][Windows] Claude Code v2.0.2 hard-freezes immediately on launch (no input; must close Terminal to quit it)
Preflight Checklist

What's Wrong?
After updating to Claude Code v2.0.2, launching claude on Windows 11 opens the TUI and then hard-freezes immediately:
- No input is accepted.
- Ctrl+C / Ctrl+Break do nothing.
- I must close the Windows Terminal tab that has it running.
This did not happen on 2.0.1 for me. I reverted with:
npm i -g @anthropic-ai/claude-code@2.0.1
What Should Happen?
The TUI should accept keyboard input, respond to commands, and allow Ctrl+C to exit cleanly.
Error Messages/Logs
None printed. The UI freezes before any output appears.claude --version prints 2.0.2 correctly, but claude doctor also freezes. Same with claude --debug
If there is a non-interactive diagnostics flag that prints and exits, I can add that output here.
Steps to Reproduce
1) claude update (or install) and confirm v2.0.2 with claude --version
2) Open Windows Terminal → PowerShell 7.5.1
3) Run claude
4) Observe: UI renders and immediately becomes unresponsive. Keystrokes have no effect. Ctrl+C does not interrupt. You must close the terminal window/tab.
Also reproduces with claude doctor.

I have waited around for several minutes as well and it never responds.
