It has been asked, answered.
But it’s not always the same answer.
For once, check if you have enough free space on your device. Android gets fussy if it doesn’t have enough free space.
If that fails, I’d recommend downloding Split APK Installer (SAI), and using that program to install the game.
For some people, that alone made the install work, but if it doesn’t, at least it will give you a more useful error message.
