xCode crashes when submitting app on El Capitan beta 5

Question

NOTE: This will look like a dupe of this question, but none of the solutions in that question have solved it. I am almost certain this is an elcap beta 5 issue, as it was not happening on beta 4.

The problem: When I attempt to upload a fresh build to iTunes connect from the organizer window, xCode crashes.

Details: It is xCode 6.4, the App Store version, not beta. The 'Submit to App Store', 'Validate', and 'Export' buttons all cause crashes. When I click each of these, the dialog for choosing a development team appears, and when I click 'choose', xCode crashes. The build number is higher than the last submission, and there are no build errors, etc.

I have attempted closing all windows except the organizer, I have tried a reboot, and I have tried the beta version of 6.4 from the dev portal; none of these things work. I have not tried xCode 7 beta, but that would be useless to me as I need to submit the build to Test Flight.

My app's release is time-sensitive, so if anyone could help me find a workaround, that would be very helpful :)

Answer 1

Archive it with Xcode 6 and then open up Xcode 7 and submit the archive from there.

Works for me
