iOS 16 beta 6 lose ActivityKit?

when it is beta 4 , it runs all right with ActivityKit and Live Activity, but when I update to beta 6 , it crash and Library not loaded: /System/Library/Frameworks/ActivityKit.framework/ActivityKit

Here the app do not crash but don't run Widgets if there is a Live Activities Widget in list.

Getting this in beta 7 as well.
