1. Check your browser console for JavaScript errors.
2. Enable WP_DEBUG_LOG and check debug.log file for PHP errors.
I opened the console and i found this.
JQMIGRATE: Migrate is installed, version 1.4.1

For PHP errors there is an error from the slider but i dont think that affect the cart.
autoptimize is a type of cache? The cart page should be excluded from caching:
https://docs.woocommerce.com/document/configuring-caching-plugins/
fyi: there’s an option in Autoptimize (which does not do page caching, just JS/ CSS optimization) to enable/ disable it on the cart/ checkout page.

Done yet but it didn’t work, same thing as before.
if the ajax cart is accessed outside of the actual cart-page, then disabling AO on the checkout/ cart page will not help.
you’ll instead have to tweak AO to exclude relevant files from JS optimization (cfr. AO FAQ for general info on how to troubleshoot & exclude JS from autoptimization). based on the console error, you would want to start by trying to exclude wow.js or wow.min.js or wow-min.js or something similar (as that seems to be breaking the JS exectution in this case)
