What's Wrong?

Environment

• Platform: Windows 11
• Terminal: PowerShell
• Claude Code version: 2.0.2
• Working version: 2.0.1

Bug Description

Claude Code 2.0.2 freezes immediately after receiving successful API responses. Downgrading to 2.0.1 resolves the issue.

What Should Happen?

Not freeze instantly. Never had issues with CLI freezing before... whole system freezing, yeah sure, but not just the CLI.
