    for short investigation and debugging The subrequest module modifies a service by incorporating the new PageCache into http_middleware.page_cache. During this process, Symfony's dependency injection is utilized, and an attempt is made to create lazy-loading virtual proxies. However, this operation encounters a failure, specifically when the Symfony proxyHelper function is invoked. This function checks various conditions such as whether the class is final, readOnly, or protected, among others. If any of these conditions are met, an error is thrown.

    Currently, I am not sure why the PageCache class added the final keyword. As a temporary solution, it might be beneficial to remove the final keyword to see if there is any need for it
