Due to old/bad logic on ::getServiceId https://github.com/mglaman/phpstan-drupal/blob/main/src/Type/ContainerDynamicReturnTypeExtension.php#L79C24-L90

Code snippet that reproduces the problem

        $cache_bins = ['page', 'dynamic_page_cache', 'render'];
        foreach ($cache_bins as $cache_bin) {
          if ($container->has($cache_bin)) {
            $container->get($cache_bin)>deleteAll();
          }
        }
