Hallo,
ich bekomme beim Shopware Update auf 6.5 (von 6.4.21) leider folgende Fehlermeldung:
PHP Fatal error: Uncaught ReflectionException: Class "Shopware\Core\Framework\MessageQueue\Handler\AbstractMessageHandler" not found while loading "SwagMigrationAssistant\Migration\MessageQueue\Handler\ProcessMediaHandler". in /XXX/vendor/composer/ClassLoader.php:582
