Hi guys, I'm testing the latest 1.4.20-dev-3947 version, which works fine in many of ours projects, but in one of them I'm getting

e: java.lang.IncompatibleClassChangeError: Found interface org.jetbrains.kotlin.ir.declarations.IrModuleFragment, but class was expected

It works just fine in 1.4.20-M2 and in jvm and js targets

I had this issue, but when i removed the android extensions plugin from the android module the project built successfully
