Can't select APK on Android 12 and up

[AndnixSH]

I encountered an issue selecting APK on Android 12 and up that I don't know how to fix them

1. File picker can't see any apk files even they are present

2. When inputting the apk path manually, the app instantly crashes, throwing this error.

You need to rewrite the application code, it is very outdated
