The same problem occurs even if you add NavigationStack to detail.

Today, I updated XCode 15.0 beta 8 and conducted a test. The problem was not resolved in XCode 15.0 beta 8. Even if this problem is resolved, using @Observable for the time being seems like a risky choice.

There is also a problem with the home screen widget. Adding 3 widgets with timers works fine at first. If you change the screen and turn the power on and off several times, some out of the three work and some do not. It seems that only the widgets of macOS and watchOS are working normally. XCode : 14.1 beta 2 (14B5024i) macOS : 13.0 beta 8 (22A5352e) iOS : 16.1 beta 2 (20B5050f) watchOS : 9.1 beta 2 (20S5049d)
