[Crash] Installation permission prompt acceptance.

[RokeJulianLockhart]

Describe the bug

Allowing Droid-ify to install untrusted applications caused Package Installer to crash:

I don't know whether the AOSP JVM needs debug symbols, nor how one would install them if so.

To Reproduce

Steps to reproduce the behavior:

1. Attempt to install https://f-droid.org/packages/us.spotco.malwarescanner/
2. After the dialog (attributed to Droid-ify, but evidently provided by the OS) to allow Droid-ify to install untrusted applications was accepted and I was taken to com.android.settings, Package Installer crashed, and Scoop caught the trace.

Smartphone :

• Device: Fairphone FP5
• OS: Android
• Version: 14, build FP5.UT20.B.041.20240624

Additional context

I'm unable to cancel the installation, now:
