What's Wrong?

Environment:

• OS: Windows (native), secondary internal drive H:\

• Claude Code version: 2.1.78

• IDEs affected: Cursor and Android Studio (JetBrains plugin beta)

Description:
Claude Code hangs randomly after reading several files sequentially. The process becomes a zombie — it cannot be stopped normally and requires force-closing the terminal. The error shown is always Interrupted · What should Claude do instead?

Reproduction pattern:

1. Open Claude Code in Windows native terminal (Cursor or Android Studio integrated terminal)
2. Execute a task that reads 3-5 files sequentially
3. After reading a large file (1000+ lines) Claude Code hangs on the next operation
4. Process stays alive but frozen, terminal shows "process is running" on close

Workaround found:
Running Claude Code under WSL (Ubuntu) accessing the same project via /mnt/h/ resolves the issue completely.

Impact: Makes Claude Code completely unusable on Windows native environment.
