claude doctor command freezes with no response to Enter key

Description

The claude doctor command hangs and becomes unresponsive. Pressing Enter does not produce any response or output.

Environment

• OS: macOS (Darwin 25.2.0)
• Terminals tested: Both iTerm2 and Ghostty exhibit the same behavior
• Date: 2026-01-23

Steps to Reproduce

1. Run claude doctor
2. The command appears to freeze/hang
3. Pressing Enter key produces no response
4. The terminal remains stuck

Expected Behavior

The claude doctor command should execute and display diagnostic information, or at least respond to user input.

Actual Behavior

The command freezes completely with no output or response to keyboard input (Enter key).

Additional Context

This issue occurs consistently across different terminal emulators (iTerm2 and Ghostty), suggesting it's not terminal-specific.

Possible Investigation Areas

• Is the command waiting for input that wasn't prompted?
• Could there be a blocking I/O operation?
• Any network calls that might be timing out?
