This might be a duplicate of Xcode crashing after archive?, but I did not see a satisfactory answer in that one. I'm running xcode 11.3.1. My app builds and runs in the simulator just fine. However, when I do Product->Archive, the archive will supposedly complete successfully and then xcode immediately crashes with SIGABRT:
UNCAUGHT EXCEPTION (NSInvalidArgumentException): *** -[NSURL URLByAppendingPathComponent:]: component, components, or pathExtension cannot be nil.
Screenshot of beginning of stack trace below -- any help or ideas would be greatly appreciated!
