With using Squarespace is there a way for me to have my site searchable without having to type www in the url?

I'm trying to publish a site with Webstudio with a domain that is now with Square Space and I get this error when trying to publish after adding the TXT and CNAME.

The domain was with a site built on Framer, I removed the domain being linked to that site so I don't think that's an issue, but I'm just not sure.
