Until recently, I was able to debug my watch app and complication, but now Xcode reports "Could not locate installed application" when I try to debug. The watch app is definitely installing correctly, because I can see the app behavior change when I make an update and then attempt to launch the debugger.
Also, whenever the app fails to launch, I see a crash log for the DTServiceHub (screenshot is too large to upload here, unfortunately).
I'm using automatic signing, and I don't think I've made any significant changes to the app or the project settings. I did upgrade Xcode a couple of days ago (to 13.3.1) and WatchOS (to 8.5.1), so either of those could have introduced the problem.
I tried reporting this on the feedback site, but the web site hangs when I try to submit a bug report (on both Safari and Firefox).
