I'm running Xcode 16.2. I'm trying to build a python project. It builds ok, but when I select "Archive", I get an error: Internal inconsistency error: never received target ended message for target ID '0' (in target '' from project ''). I can Clean Build Folder and Build, but I can't Archive (to create an object to export to App store)

I need a simulator for iOS 16.7.10 to get a program to run on my old iPad. It looks like I can only get simulators for iOS 16.0-16.4, is that right?
