Slider disappear once published on mobile

Hello everyone.

I have trouble with the slider on my homepage. Everything works well on all devices unless on mobile devices on which, once published, the slider disappears (cf pictures).

I first thought it was a sizing problem but cannot figure out if it’s the case as all my attempts to solve this is inefficient.

Thank you in advance for your help, I am really lost!
