You tap the app icon.
The screen doesn’t change.
No error.
No loading screen.
If you check recent apps, the app appears for a second.
Then it disappears again.
This feels strange because the app is technically running.
It just never stays visible.
In many cases, the app starts in the background but fails to move forward.
The system launches it, but the screen is never allowed to take focus.
This often happens when the app’s launch process is interrupted.
A background task starts successfully.
The foreground step never completes.
The app is not frozen.
It is not crashing.
It exits the foreground before you ever see it.
This behavior is common after system updates, permission changes, or task restrictions.
The app opens—but only behind the scenes.
From the user’s side, it looks like the app refuses to open.
In reality, it never finishes coming to the front.
