How to clear cache Laravel?

I tried these commands:

php artisan config:cache  

php artisan route:cache  

php artisan cache:clear

All of them return me error:

Class 'App\Providers\InvitationServiceProvider' not found

But I dont have InvitationServiceProvider anywhere in project.

So, how to rebuild Laravel?

Also I tried composer dump and php artisan serve
