Erro Na exclusão de registro

PHP Fatal error:  Uncaught Error: Class 'Alura\Cursos\Infra\EntitymanagerCreator' not found in /media/felipe-pc/Backup/cursos alura/PHP-MVC/cli-config.php:6
Stack trace:

Já usei o comando php vendor/bin/doctrine orm:generate-proxies

também já dei permissão na pasta temp sudo chmod a+w /tmp

mais ainda quando tento excluir um registro, gera o seguinte erro
