Hero Banner, Navigation and social share stopped loading

Hi, for 1-2 weeks we have the issue now, that the hero banner (now switched off), the social media share buttons (above the image) on individual posts and the navigation dropdown are no longer loading/displaying.

We’ve had this before with Jetpack causing the issue, but this time can’t figure out what is causing it.

Is there any way for you to easily locate the plugin or error, which might cause those 2 things from loading?

Additionally, I’ve come across this error, not sure if they are related

Uncaught TypeError: $(…).stacktable is not a function
at Object.wpreview.initResponsiveTable (main.js:66)
at HTMLDocument.<anonymous> (main.js:75)
at i (jquery.js:2)
at Object.fireWith as resolveWith
at Function.ready (jquery.js:2)
at HTMLDocument.K (jquery.js:2)

Your quick help would be appreciated.
