What's Wrong?

Environment

• Claude Code version: 2.1.78
• OS: Windows 11, WSL2
• Node.js: v18.20.8 (via nvm)
• Project location: /mnt/c/ (Windows filesystem)

What's wrong
After auto-updating to 2.1.78, every task gets interrupted mid-execution
with "Interrupted · What should Claude do instead?" — even plain
conversational questions with no file reads. Typing "continue" does not
help. Restarting the computer does not help.

Steps to reproduce

1. Auto-update to v2.1.78 on WSL2
2. Open any project
3. Ask Claude to read files or even ask a simple question
4. Observe "Interrupted" after every tool call

Expected behavior
Tasks complete without interruption.

Actual behavior
Every session is interrupted, making Claude Code unusable.

Fix
Downgrading to v2.1.62 (stable) resolves the issue completely:
npm install -g @anthropic-ai/claude-code@2.1.62

What Should Happen?

Tasks complete without interruption.
