Describe the bug
The application crashes forcefully with a NullPointerException while operating with Shizuku privileges. The crash occurs on the main thread when a Runnable (executed via Handler) attempts to invoke the .add() method on an uninitialized CopyOnWriteArrayList object.
Note: This is a persistent and 100% reproducible issue. The app crashes every single time an installation is attempted, regardless of the APK file chosen. I have also experienced the exact same crash on my previous device running Android 14, indicating it is not an OS-specific issue but a core bug in the Shizuku installation flow.
To Reproduce
Steps to reproduce the behavior:
Ensure Shizuku service is running and permission is granted to the package manager.
Select any APK file from storage to install.
Grant the "Install unknown apps" permission.
Proceed with the installation.
The app immediately crashes.
Logcat / Stacktrace
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.util.concurrent.CopyOnWriteArrayList.add(java.lang.Object)' on a null object reference

Environment:
OS / Android Version: Android 16 - HyperOS 3 (May Security Patch)
Previous OS Tested: Android 14 (Issue also persists here)
Mode: Shizuku
Additional technical context
Based on the trace, the issue originates inside the obfuscated class u7 at line 219. It seems a list used for holding data (likely related to the installation queue or package parsing via Shizuku) is declared but not properly initialized with new CopyOnWriteArrayList<>() before a background task attempts to push data to the UI thread via a Handler callback.
