I can't save my classnames, because of the error "A class was removed from your site and is no longer active on this element" after going back to Elementor v4

My problem:

I add a classname to a widget (like a div, etc)
I create a classname to apply to this widget with some CSS inside it
I published the project
When reloading the website, or going back to it where I want to edit the page with Elementor, in the Classes section, it says "A class was removed from your site and is no longer active on this element"

What should I do to fix it?! Any workaround?

Elementro version: 4.3.0

Elementro Pro version: 4.3.0

WordPress version: 7.1.2

PHP version: 8.2.33
