I'm getting exactly the same issue as you describe. If I have over ~70 slides, swiping through the slides on Safari iOS (iPhone 13 mini 26.0.1) will cause it to crash with the following message, `A problem repeatedly occurred on "https://192.168.0.210/bins/008b1c6-4463-4b94-862b-7d74d22dab3e/".` (For those reading this, the URL is irrelevant.)
I'm assuming this must be an issue of scale. And indeed it is. Looking at the swiper documentation at https://swiperjs.com/swiper-api#virtual-slides , it looks like Virtual slides was specifically designed to tackle this issue of scale. Heck, even their demo over at https://swiperjs.com/demos#virtual-slides shows 600 slides to prove the point. After I enabled Virtual slides, the issue instantly went away!
