Getting error after adding arguments in constructor

Question

I have added model in my constructor

public function __construct(
    Context $context,
    PageFactory $resultPageFactory,
    \Vendor\Module\Model\Productsgrid $model
)
{
    $this->model = $model;
    $this->resultPageFactory = $resultPageFactory;
    return parent::__construct($context);
}

After adding model I am getting this error:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function...

When I am removing Productsgrid model it's working fine, am I doing something wrong?

This happens with me before. You need to run upgrade dicompile and full deployment script

php -dmemory_limit=1G bin/magento setup:upgrade
php -dmemory_limit=1G bin/magento setup:di:compile
php bin/magento deploy:mode:set developer --skip-compilation
php bin/magento setup:static-content:deploy --theme Magento/backend -f
php bin/magento setup:static-content:deploy --theme Naheed/NaheedTheme -f
php bin/magento cache:clean

This will resolve your issue
