Answer

That’s not how you render a controller.

{{ render(controller(
        'App\Controller\ArticleController::recentArticles',
        { 'max': 3 }
    )) }}

It’s clear from the doc

To include the controller, you’ll need to refer to it using the standard string syntax for controllers (i.e. controllerNamespace::action):
