Xcode 6 crashes on submitting Archive

Question

Today I uploaded my first build of first app successfully to App Store for beta testing. After making a few changes, when I tried to submit the new archive again Xcode crash

Answer 1

I had the same issue at June 17 night. I reinstalled my Xcode, and had the same issue. Looks like Apple updated something at that day, since I noticed the website of Member Center, the MAC certificate is also there. (YES!!! apple only charge once for iPhone and Mac)
