Could you please take a look at the event viewer to check if the app is failed to launch due to some error?
After check it. It's not has error log, and it can be launch without MS digital sign app package.
Please submit feedback about this behavior on the Feedback Hub. You could find the Feedback Hub in the Start Menu.
HI LimitlessTechnology-2700
Thank you for your reply.
This appx package will publish to MS store for all user.
I want to offline test signed package before publish to MS store.
This behavior could be on Windows 10, but Windows 11 could not work.
So I want to check this installed behaviro was changed on Windows 11 or not.
