Same as the few above answers: "Clearing the cache manually fixes this issue for me, Open finder on your mac, and click on Go -> Go to Folder And paste this "~/Library/MobileDevice/Provisioning\ Profiles/" delete all items restart xcode and retry" Worked for me! Successfully uploaded new build

I am having the same issue as well: "beta 3, now it started for Combine framework too" as posted by Hiren Gujarati above.
