Issue in php artisan config:clear in Laravel

I run php artisan config:clear or php artisan cache:clear or composer dump-autoload But show this error:

PHP Fatal error:  Uncaught ReflectionException: Class App\Console\Kernel does not exist in 
vendor/laravel/framework/src/Illuminate/Container/Container.php:767
Stack trace:

Laravel version is 5.6

Show this error after run php artisan config:clear
