Laravel (5.6) Service Poviders

So I have been disabling certain services in my laravel application.

But when I disabled QueueService Provider since I was not using queue service and tried running artisan commands it displayed error "Class queue.listener not found" can some one tell me where is it (QueueServiceProvider) being used by the application ?.

The same happens if I disable TranslationServiceProvider stating Class translator not found. I remove all __() operators from laravel auth scaffoldings.

Help needed thank you.
