Some sort of conflict with Elementor Pro and Fusebox?

Hello,
After installing RankMath, Elementor Pro started acting oddly. It stopped showing design changes I make to the site and my error log shows some kind of issue with the podcast player. Here’s the error log:

Elementor Pro and Fusebox.fm are essential plugins for this site. If Rankmath is incompatible with one of them, please let me know.

Do you have any idea what can be done to fix these errors?

Thanks in advance!
