Does anyone know how to resolve this?

This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 4.3 or newer.

IntelliJ IDEA's android plugin is older than the one that comes with Android Studio, which is why it can't open the project.

if you're opening a KMP project with android studio, should you be importing the top level build.gradle or just the android build.gradle?
