Website crashes on iPads

Hi there,

We have reports from multiple users of a client’s site that the Minicorp theme is crashing on their iPad.
It happens at random intervals and pages, which makes it very hard to research.
Seemingly it happens more in portrait mode than in landscape mode.

The website hangs shortly, stops working and Chrome/Safari closes itself.
When re-opening the browser, the website is still there and works normally, but it opens not necessarily on the last visited page.

Our client’s site is https://ovvia.nl/.
Is this something you recognize/have experienced before?
Where in the code can I start troubleshooting this problem?
Can it be the slider crashing the website?

Thanks in advance,

Jelmer
