failed to open DevTools URL: {error}

Error message

failed to open DevTools URL: {error}

What it means

Wrapped failure thrown by the launcher's open_url helper on Windows: codex_plus_core::windows_open_url failed and the error is wrapped as "failed to open DevTools URL: {error}". The {error} is the underlying ShellExecute failure; the offending input is the devtools:// URL built for the selected CDP target that the OS refused to open.
