CRITICAL Uncaught Error (Elementor.php)

Greetings,

I’m getting this in my error logs:

CRITICAL Uncaught Error: Call to a member function is_edit_mode() on null in /home/cloudwaysapps.com/mydomain/public_html/wp-content/plugins/quadmenu/includes/3rd/elementor.php:40

Any idea what may be causing this?
