The issue is with the malfunction of Autoplay feature when altering slidesPerView on Swiper.js.

edit

This could be due to a bug in the Swiper.js library or a conflict with other code on the page.

To troubleshoot the issue, try the following:

1. Check the console for any error messages related to Swiper.js or Autoplay.
2. Make sure you are using the latest version of Swiper.js.
3. Try disabling any other scripts or plugins on the page to see if they are causing a conflict.
4. Experiment with different values for slidesPerView to see if that resolves the issue.
5. Check the Swiper.js documentation or GitHub repository for any known issues or workarounds related to Autoplay and slidesPerView.

If none of these steps resolve the issue, you may need to reach out to the Swiper.js community for further assistance or consider using an alternative carousel/slider library.
