PHP Fatal error on update BuddyPress 5.x / WP 5.3.x

This error broke wp-admin/plugins.php and wp-admin :

PHP Fatal error: Uncaught Error: [] operator not supported on main plugin file, line 155.

I manage to resolve it by adding this workaround :

                    $notices = get_option('bxcft_notices');
                    if ( empty( $notices ) ) {
                        return false;
                    }
