Class ShoppingCart not found

Env infos: Apache 2.4.27, PHP 7.1.9, Laravel 5.7, MySQL 5.7.19, Windows Pro. I was writing some translations into file Corals\modules\Marketplace\resources\lang\pt-br\labels.php, also creating some new settings to Store at Corals\modules\Marketplace\config\marketplace.php, when I started to figure out error 500, from NOTHING. Before this strange behavior, everything was fine. In laravel.log, the error is similar as below, but claiming for ShoppingCart class, not theme. I have no clue what's going on. I tried clean all cache from storage/framework, no success.
