I confirm, same thing i have, just by switching inspect from web to mobile, then back to web & i got it.

Anyway there's no clear example on how to use Lazy module, so i've reverted to "swiper": "^8.4.7",

Same here :(
edit - can also confirm that reverting back to "swiper": "^8.4.7" fixes the issue for now
