CORB Adsense?

It turns out that there are a lot of such CORS errors, the font is not even loaded from my domain. Could the Real Amp URL be the reason for this?

Thanks for reaching out. In most cases such HTTP blocked responses can be disregarded as they don’t impact how your AMP site renders, in particular I don’t see anything specific to ads. If you want to share your site URL I can take a quick look.
