IMPORTANT All the compatibility issues between Premium Carousel widget and Elementor v3.5.0 have been resolved in Premium Addons for Elementor v4.7.6. So, please make sure to update your version to get things back to work.
This issue usually occurs due to `Stretch Section` option in Elementor Section settings, this option actually uses JS to stretch your section so, you can simply fix that just by disabling this option for section templates you are using inside the carousel widget.
