Thanks for the further explanation.
We use the swiper js library available within Elementor. So in our widgets, we define it as a dependency, and Elementor loads it wherever required.
If you are loading swipers from your own then it might be conflicting with the one already loaded by Elementor and breaking all its implementations.
You can either try to load swiper js conditionally or load only if no other instance is loaded.
Also make sure to load the same library version that is loaded by Elementor. Version mismatch also causes such conflicts.
