Xcode Cloud - Connecting Xcode Cloud with your source control provider was incomplete

While trying to configure Xcode Cloud I am stuck in a continuous loop. When I setup the project in Xcode and click “Grant Access”, it navigates me to AppStore Connect on the screen showing “Select Source Control Provider”, “Gitlab Self-Managed” is showing as connected, but its not.

When I initially tried to setup, the configuration failed and since then its shown as connected. If I then click on GitLab Self-Managed to re-connect and continue the setup process, but after a few moments an error message is displayed saying.

What I would like to do, is delete the connection and re-connect but can't see anywhere within options that its actually connected other than this page.

Though when click on the "SelfHosted Option", I get this. “Connecting Xcode Cloud with your source control provider was incomplete. An unexpected issue has occurred. Please try again.”.
