Xcode 7.1 crashes when opening Organizer (Dispatch queue: Cache and App Store Product Source Lock)

I just installed Xcode 7.1 GM and OS X 10.11.1. When I tried to archive one of my projects to submit it to the App Store, it crashed upon finishing the archive right as the Organizer window was opening. Now I can't open the Organizer window at all. The crash log references "Dispatch queue: Cache and App Store Product Source Lock" and an assertion failure in DVTInvalidation.m.


Would appreciate some kind of workaround ASAP, as this is preventing me from submitting to the App Store!
