Trying to install/update an APK via Installer results in a stuck notification without prompting for installation

Please check before submitting an issue

• I have read CONTRIBUTING.md and the relevant sections of the ROADMAP.md.
• I am running the latest AppManagerNG release from GitHub Releases, IzzyOnDroid, or Obtainium (not an upstream App Manager build).
• I have searched open and closed issues and could not find an existing report.
• I can reproduce the issue and have collected the support-bundle fields below, or have noted what is missing.

Describe the bug

I tested the installation process on several APKs. The window with information about dangerous permissions, etc., appears normally. I don't have root access, so confirming the system and using the system installer is necessary.

So I tap Install, and a notification from AMNG appears about the installation process starting, with the progress bar at 100%. The progress bar keeps scrolling, but the system prompt for installation doesn't appear. I waited 5 minutes. Usually, 2 seconds is enough. All the necessary permissions were granted, of course.

Then I revoked permission to install programs in the firmware. AM should ask for permission automatically in this situation, right? But when I tried to install (after force-stopping), the symptoms were exactly the same: notification, 100%, stuck... I manually granted permission again, force-stopped, and restarted AM — nothing changed.

Of course, all apk files can be installed/updated normally using regular AM.

I also can't uninstall the installed APK - the system installer's request to delete the package doesn't appear.

Steps to reproduce

Everything has already been described above.

Expected behavior

Normal system installer prompt and normal completion of the installation process.
