Add this Code to vendor\Module\Controller\Index/Index.php

    <?php
    namespace vendor\Module\Controller\Index;

    use Magento\Framework\View\Result\PageFactory;
    use Magento\Framework\App\Action\Context;

    class Index extends \Magento\Framework\App\Action\Action {

        /**
         * @var \Magento\Framework\Controller\Result\ForwardFactory
         */
        protected $resultPageFactory;

        /**
         * @param \Magento\Framework\App\Action\Context $context
         * @param \Magento\Framework\Controller\Result\ForwardFactory $resultForwardFactory
         */
        public function __construct(
        \Magento\Framework\App\Action\Context $context, \Magento\Framework\View\Result\PageFactory $resultPageFactory
        ) {
            $this->resultPageFactory = $resultPageFactory;
            parent::__construct($context);
        }

        public function execute() {
            $resultPageFactory = $this->resultPageFactory->create();

            // Add page title
            $resultPageFactory->getConfig()->getTitle()->set(__('Sample Module'));

            // Add breadcrumb
            /** @var \Magento\Theme\Block\Html\Breadcrumbs */
            $breadcrumbs = $resultPageFactory->getLayout()->getBlock('breadcrumbs');
            $breadcrumbs->addCrumb('home', [
                'label' => __('Home'),
                'title' => __('Home'),
                'link' => $this->_url->getUrl('')
                    ]
            );
            $breadcrumbs->addCrumb('custom_module', [
                'label' => __('Test'),
                'title' => __('Test')
                    ]
            );
            return $resultPageFactory;
        }
    }
