Why I can't install the 13.2??

PC, Mac, Linux, Android?
Assuming Android... Check that you have enough space to install the APK.
Android being Android and Android being weird, you most likely need from 2 to 4 times the size of the APK, so at least 4GB of free space to properly install the APK.
You can backup your saves by going to this route with a file explorer:
Android/data/com.domain.corruptedkingdoms/saves
You will probably need a file explorer like SolidExplorer if you're on android 10 and after.
After making a backup of your saves you can uninstall the app, install the new version and move the saves back where they belong.
