[BUG] Claude Code hangs silently with corrupted config instead of showing clear error

What's Wrong?

Claude Code hangs indefinitely with no output when configuration files are corrupted. The only indication is an unhelpful error in debug logs: lK is not a function.

## Steps to Reproduce

1. Have a corrupted file in ~/.claude/ directory (cache, statsig, etc.) or corrupted ~/.claude.json
2. Run claude or claude login
3. Process hangs with blank screen - no output, no error message

## Expected Behavior

Claude should either:

• Display a clear error message indicating which config file is corrupted
• Offer to reset/clean the corrupted configuration automatically
• At minimum, not hang silently

## Actual Behavior

• Claude hangs indefinitely with no output
• Debug logs (~/.claude/debug/latest) only show:

Failed to check enabledPlatforms: TypeError: lK is not a function

• No indication of what's wrong or how to fix it

## Workaround

Partial fix (doesn't always work):
```bash
rm ~/.claude/.credentials.json

Full fix (not always works):
rm -rf ~/.claude ~/.claude.json
claude login

Additional Context

• Tested on multiple servers with same result
• Tested versions: 2.1.5, 2.1.18, 2.1.20 - all exhibit same behavior
• The error lK is not a function appears to be minified code that fails to check platform configuration when config state is inconsistent

Environment

• OS: Linux (RHEL/CentOS)
• Node: v18.20.8
• Claude Code: 2.1.20

What Should Happen?

Claude should detect corrupted configuration files and display a clear error message like: "Configuration file ~/.claude/cache/xxx is corrupted. Run 'rm -rf ~/.claude' to reset." Instead of hanging silently, it should either auto-recover or guide the user to fix the
issue.

Error Messages/Logs

Steps to Reproduce

1. Create a corrupted state by having invalid/inconsistent files in ~/.claude/ directory

(This can happen naturally when OAuth token expires or session is interrupted)

1. Run: claude login

1. Observe: Process hangs with blank screen - no output, no prompt, nothing

1. Check debug log: tail ~/.claude/debug/latest

Shows only: "Failed to check enabledPlatforms: TypeError: lK is not a function"

1. Workaround that does NOT fix it:

rm ~/.claude/.credentials.json
claude login
# Still hangs

1. Workaround that DOES fix it:

rm -rf ~/.claude ~/.claude.json
claude login
# Works - shows login prompt
