I see that this is still an issue on macOS 27 Golden Gate betas. I have filed a report. Feedback ID FB23841498.

It points to a crash on @main on my AppDelegate class (WKApplicationDelegate). There isn't much in the debugger other than: Couldn't instantiate class _TtC30PDX_Transit_WatchKit_Extension23MainInterfaceController Any ideas of where I can begin with this? Xcode 14 Beta 3
