Bug Report

OS: Windows 11 Pro Shell: bash (Claude Code terminal) Claude Code version: latest channel

Steps to Reproduce

  1. Open a Claude Code session
  2. Run /config
  3. Close/exit the config UI
  4. Run /config again in the same session

Expected Behavior

Config UI opens normally on second invocation.

Actual Behavior

The entire Claude Code session freezes. No further input is processed. Terminal restart required to recover.

Additional Context

Reproducible consistently. First /config invocation works fine — freeze only occurs on the second call within the same session.

extent analysis

TL;DR

The issue may be resolved by modifying the configuration loading process to handle multiple invocations within the same session.

Guidance

  • Investigate the configuration loading mechanism to identify potential resource leaks or locks that could cause the freeze on subsequent /config calls.
  • Verify if the issue persists when running /config in a new Claude Code session, to determine if the problem is session-specific.
  • Check for any error messages or warnings in the terminal output before the freeze occurs, which could provide clues about the underlying cause.
  • Consider adding a debug flag or logging to the /config command to gather more information about the freeze.

Example

No code snippet can be provided without more information about the internal implementation of the /config command.

Notes

The issue seems to be related to the internal state of the Claude Code session, and modifying the configuration loading process may require changes to the underlying code.

Recommendation

Apply a workaround, such as restarting the Claude Code session after each /config invocation, until a more permanent fix can be implemented, as the root cause of the issue is not yet clear.
