You open the app.
The logo flashes for a second.
Then the app disappears.
You never see a login screen.
No error message.
No warning.
This kind of crash happens before you can enter an email or password.
That detail matters.
At this stage, the app is preparing its authentication system.
It checks stored sessions.
It loads account frameworks.
It verifies whether a login screen should even be shown.
If something fails during this preparation, the app shuts down immediately.
It never reaches the point where you can interact.
This is common when:
• Old login data is corrupted
• A previous session was never fully cleared
• The authentication service fails silently
From the user’s perspective, it looks random.
In reality, the app is stopping itself because the login flow cannot be safely initialized.
That’s why reinstalling sometimes works.
It forces the app to rebuild the login state from zero.
If the app closes before the login screen appears, the crash is happening inside the authentication setup—not after login.
