I figure out why Android 14 OS can not install the apk. Because since Android 14, the developer upgraded the system security and privacy protection mechanisms. Any app, witch "targetSdkVersion" lower than 23 can not be installed on any Android 14 OS.
If you want to install the Dune apk on Android 14 OS, you should use the developer model of your equipment, and through the USB debug mode, open the USB install on your Android. Then download and install windows "adb" on your pc, configure system environment variables of the "adb". Then use the cmd window on your pc to install the apk on your Android.
The apk should on you pc, not your Android equipment.
The code to input in the cmd window is: adb install --bypass-low-target-sdk-block X:\XXX\XXX.apk
The X were not the same if you put the apk on your pc in different path.
Windows "adb" download:
