Codex Crash

Open 💬 2 comments Opened Jun 27, 2026 by nmwcharran-jedi

Codex desktop app crashes immediately after updating to version 26.623.42026 on macOS.

The crash occurs during plugin startup with:

(code=null, signal=SIGKILL)

The app repeatedly reports invalid bundled plugin manifests, including errors such as:

  • interface.defaultPrompt: maximum of 3 prompts is supported
  • prompt must be at most 128 characters

Affected plugin paths have included:

  • template-creator
  • ngs-analysis

I have already tried:

  • rebooting macOS
  • clearing Codex runtime caches
  • clearing temporary plugin caches
  • moving aside ~/.codex/config.toml
  • disabling template-creator in config.toml
  • rebuilding the Codex plugin/runtime cache

The issue persists even after the configuration/cache reset. My local Xcode project is unaffected.

Please investigate whether build 26.623.42026 has a bundled-plugin or plugin-loader regression on macOS.
