Solved This issue was not caused by Xcode or project configuration. I contacted Apple Developer Technical Support and provided my Apple Developer account role (Admin), the Xcode IDEDistributionProvisioning logs, and screenshots from Xcode Organizer showing the Archive failure. After investigation, Apple confirmed that the root cause was an App Store Connect API–related permission issue that required a backend update on their side. Once the backend permissions were updated, I retried the Archive process. Xcode was then able to correctly create and use the Cloud-managed Distribution Certificate and generate the App Store provisioning profiles, resolving the issue. If you encounter the same error (403 Forbidden, ResultCode 7495, unable to use Cloud-managed Distribution Certificates even as an Admin), contacting Apple Developer Technical Support with the IDEDistributionProvisioning logs and Archive error screenshots is recommended, as this appears to be a backend permission issue.
