Declaration of Interceptor::execute() must be compatible with Detail::execute():

I’m trying to display a simple page, but still getting this error.

Fatal error: Declaration of MacademyBlogControllerPostDetailInterceptor::execute() must be compatible with MacademyBlogControllerPostDetail::execute(): MagentoFrameworkViewResultPage in /var/www/html/generated/code/Macademy/Blog/Controller/Post/Detail/Interceptor.php on line 19

PHP 7.4.30

Magento 2.4.5

<?php
declare(strict_types = 1);

namespace MacademyBlogControllerPost;

use MagentoFrameworkAppActionHttpGetActionInterface;
use MagentoFrameworkViewResultPage;
use MagentoFrameworkViewResultPageFactory;

class Detail implements HttpGetActionInterface {

    public function __construct(
        PageFactory $pageFactory
    ) {
        $this->pageFactory = $pageFactory;

    public function execute(): Page {
        return $this->pageFactory->create();
    }
