Rankmath causes Elementor widget panel loading issues.

I've googled the problem and tried everything. Created staging and it seems that rankmath(I only have free version) is the issue. Elementor free and pro are up to date as well as rankmath. As long as I deactivate rankmath I can work on the website but I don't like doing this every other day. Online they say that the issue has been fixed on the last release but it hasn't it seems. Any other suggestions please?
