After using xcode 15 for distribution we are having strange crashes from UICollectionViewDiffableDataSource. Crash does not indicate any call stack from our own code. This happens on %100 ios 17 and with xcode 15.1 build and we can not reproduce it in testing environment. Here is the stack trace

Hello everyone. There is really annoying regression in xcode 14 and 14.1 beta. We have a large modularized workspace. In workspace there is one ios app target that hosts xctestplan that contains over 50 unit test targets. When we try to run tests with cmd+u xcode immidately freezes and force quit is required. This was not an issue with xcode 13.
I tried to run tests via command line with xcodebuild. This time it stucks at prepare packages stage before building any target. After about 7-10 minutes it continues building targets. So I am guessing there is something wrong with resolving target dependencies in xcodebuild.
Anyway this is super frustrating for us and it holds us back to moving xcode 14. Is there other people experiencing the same issue with xcode 14? Did you find any workaround?
