Solution

Your controller file is wrong. Please replace with this code.

<?php

namespace MyModule\ProxyQuote\Controller\Index;

use Magento\Framework\App\Action\Action;

class Config extends \Magento\Framework\App\Action\Action
{
    protected $resultPageFactory;
    protected $logger;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Psr\Log\LoggerInterface $logger,
        \Magento\Customer\Model\Session $customerSession
    ) {
        $this->resultPageFactory = $resultPageFactory;
        $this->logger = $logger;
        $this->session = $customerSession;
        parent::__construct($context);
    }

    public function execute()
    {
        $resultPage = $this->resultPageFactory->create();
        $resultPage->getConfig()->getTitle()->set(__('Show You Page'));
        return $resultPage;
    }
}

I Hope This Help You.
