We solved it in this post – https://wordpress.org/support/topic/critical-error-314/
The last comment has a link to download a patched version.
This plugin is relying on some depreciated functions in Elementor.
You need to replace all instances of “use Elementor\Scheme_Typography;” with “use Elementor\Core\Schemes\Typography;” and change all “Scheme_Typography::” to “Typography::”
Same for Scheme_Color.
