Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

Yes

Description

I have an Angular 17 Webapp and we use it together with the Ionic/Capacitor Framework to build a native android app.

When starting the app on an Android Device with Android 12 or lower, there are error messages in the logcat and the app just shows a white screen.

This is not the case and the app works fine on devices/emulators running Android 13+.

Please provide a link to a minimal reproduction of the bug
