Gitlab account deleted error on creating new Cloudflare Pages Site

I used to have a GitLab account that I must have deleted at some point. But did not delete the associated cloudflare page. Now I wish to again start a cloudflare page with my GitHub account. However to start a new page on the

Workers and Pages → Overview → Pages → Connect to Git

page, I get the error:

Your GitHub/GitLab account has been blocked. (Code: 8000050)

What to do? I would like to use a GitHub account that I now have access, instead of the GitLab account that I lost access to and was apparently linked here to Cloudflare Pages.
