When I accept the default I get the error
App record creation failed due to request containing an attribute already in use. The App Name you entered is already being used. If you have trademark rights to this name and would like it released for your use, submit a claim.
I couldn’t figure out what was happening so I tried to start over from the beginning with a nonsense name and got the same error.
I’m using XCode 14 and macOS Ventura 13.2.1
