What's Wrong?

Claude Code version: 2.1.69 (broken), 2.1.64 (working)
OS: Windows 11, native (not WSL)
Terminal: PowerShell / Command Prompt

Bug Description

After selecting "Yes, I trust this folder" on startup, Claude Code hangs indefinitely with no error shown. Ctrl+C kills the process but it hangs again on every subsequent restart. Affects every directory.

Root Cause (from debug log)

The config lock mechanism is trying to mkdir 'C:\Users\jon.pardeck' (the user home directory itself), which already exists, causing a silent EEXIST error loop. The error repeats dozens of times with no message surfaced to the user — the UI just freezes.

[ERROR] Failed to save config with lock: Error: EEXIST: file already exists, mkdir 'C:\Users\jon.pardeck'

Stack trace from ~/.claude/debug/latest:

Workaround

The npm-installed version at %APPDATA%\Roaming\npm\claude (2.1.64) works correctly. The native installer binary at %USERPROFILE%\.local\bin\claude.exe (2.1.69) is the broken one. Downgrading via npm and ensuring it takes PATH priority resolves the hang.

npm install -g @anthropic-ai/claude-code@2.1.64

Steps to Reproduce

1. Install Claude Code 2.1.69 via native installer on Windows
2. Run claude in any directory
3. Select "Yes, I trust this folder"
4. Claude Code hangs — no prompt appears, no error shown, process must be killed
