See title. I have tried lots of things already, including a complete reinstall of Wordpress. Whenever I try to load the Elementor editor I get the following error: VM4190:6 Uncaught TypeError: $e.components.get(...).utils.allowAddingWidgets is not a function at eval (eval at template

I have another similar install where all core files are the same. Deactivating, uninstalling and reinstalling Elementor does not work either, always get back to the same issue. I have tried disabling and clearing the WordPress cache but that does not seem to work as well.
