Removing a service provider breaks the site?

Question

Laravel

After removing the service provider, the page gives an http500 error, and no more errors at all (even the standard laravel error page is not displayed). Tried cache:clear, composer dump-autoload, removed service provider registration from config/app.php, all file permissions are set fine. What is the problem? Error in logs:
