As you said in another thread, you check is WooCommerce active. That is not sufficient – you need to hook into woocommerce_loaded.

Update your addons.php file with:

// WooCommerce Attribute order.
add_action(
	'woocommerce_loaded',
	function() {
		add_action( 'to/get_terms_orderby/ignore', 'to_get_terms_orderby_ignore_woocommerce', 10, 3 );
	}
);
function to_get_terms_orderby_ignore_woocommerce( $ignore, $orderby, $args ) {
	
	// Create a list of attribute taxonomies.
	$attributes           = wc_get_attribute_taxonomies();
	$found_attributex_tax = array();
	foreach ( $attributes    as  $attribute ) {
		$found_attributex_tax[] = 'pa_' . $attribute->attribute_name;
	}

	if ( ! isset( $args['taxonomy'] ) || count( $args['taxonomy'] ) !== 1 ) {
		return $ignore;
	}

	if ( count( array_intersect( $found_attributex_tax, $args['taxonomy'] ) ) < 1 ) {
		return $ignore;
	}

	return true;

}
