Getting error in RendererFactory.php right after the installation

Right after succesful installation I can´t open Magento admin because I´m getting: C:\xampp\htdocs\www\vendor\magento\module-developer\Model\View\Page\Config\RendererFactory.php on line 70

(From debug.log)

Same error appears when I try to load homepage.

Line 69 & 70: return $ this->objectManager->create( $ this->rendererTypes[$ renderer],

Thanks for advice.
