my case was the same, it seems you forgot to select Certificates, Identifiers & Profiles when adding you to Apple store Connect , I fixed it by re-adding my account to applestoreconnect, and don't forget to select Certificates, Identifiers & Profiles. you can check the link: https://developer.apple.com/account/resources/certificates/list to know if you have this permission, updating this permission may take 10 minutes, please wait for mail response and re-login in XCode.
i hope it helps you
