Can you please enable remote debugging?
Pretty strange.
The same error is reported also for gdpr cookie compliance plugin:
https://www.italiaslowtour.com/cms/wp-content/plugins/gdpr-cookie-compliance/dist/scripts/main.js
I can’t reproduce the problem on my test installation.
Will prepare a version with additional debugging info.
after delete and reinstall : same problem. 🙁
Very strange.
It seems the issue you have has nothing to do with the plugin.
1. The same ad code with the same settings runs fine on test servers.
2. The same error is reported also for gdpr cookie compliance plugin for this script:
/wp-content/plugins/gdpr-cookie-compliance/dist/scripts/main.js

I can’t imagine the same error in two different plugins.
Therefore it must be something with your website.
I would need to look deeper.
