I want to stop redirecting the success page and stay the same page when the refresh page.

You can stop checkout success page redirection after refresh page, check below code

vendor/magento/module-checkout/Controller/Onepage/Success.php

Kindly open Magento\Checkout\Controller\Onepage\Success.php and comment below line

You can also install the Magepal module which works perfectly without any code modification. Make sure to install it as a dev requirements:

You can stop checkout success page redirection after refresh page, check below code

vendor/magento/module-checkout/Controller/Onepage/Success.php

Comment Out Line No : 22 And in Magento 2.3... Line No : 26

//$session->clearQuote();

Ex :-

public function execute()
    {
        $session = $this->getOnepage()->getCheckout();
        if (!$this->_objectManager->get(\Magento\Checkout\Model\Session\SuccessValidator::class)->isValid()) {
            return $this->resultRedirectFactory->create()->setPath('checkout/cart');
        }

        // $session->clearQuote();            ***** COMMENT THIS LINE *****

        //@todo: Refactor it to match CQRS
        $resultPage = $this->resultPageFactory->create();
        $this->_eventManager->dispatch(
            'checkout_onepage_controller_success_action',
            [
                'order_ids' => [$session->getLastOrderId()],
                'order' => $session->getLastRealOrder()
            ]
        );
        return $resultPage;
    }

Now you can debug checkout success page.
