failed to create directories for settings file: {e}

Error message

failed to create directories for settings file: {e}

What it means

Filesystem guard in CliSettings::save: creating the parent directory chain for the global CLI settings file (via fs::create_dir_all) failed, so the serialized settings cannot be written. This is an environment/permissions failure on the settings directory path — the input at fault is the settings file's parent path reported alongside the OS error.
