Building an AI-assisted module with open-source AI-Task-Manager.

Hey guys,

somehow my content looks kind of weird since a few days. The gaps between the text got less and I can't edit the text directly in the cms.

I get this error "Your site doesn’t include support for the "core/group" block. You can leave this block intact, convert its content to a Custom HTML block, or remove it entirely."

In the system tab it says that there are updates available. The problem is I'm an SEO and my client thinks I've breaked the page even though all I did, was changing the CMS content. (Text and Internal Links)

Could this have been caused by me? Or is this a deeper problem.
