Having issue with closing button

Hi,

We are facing a weird issue. When we try to close the popup (triggered from “Produkt anfragen” button) we have to click twice to close.

Also when we click the close button this JS error appears in the console

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'setAttribute')
    at e.value (custombox.min.js?ver=2.0.6:9)
    at custombox.min.js?ver=2.0.6:9
    at async Promise.all (/de/produkte/ventilsteuerung-filtersteuerung/ventilsteuerung-he-5711-gehaeuse/index 0)
https://www.hesch-automation.com/wp-content/plugins/popup-anything-on-click/assets/js/custombox.min.js?ver=2.0.6

We are using WP Rocket for caching, we tried to exclude the js from Wp Rocket, but it didn’t worked.

Thank you.
