Just downloaded and installed CHelper v4.4.2 (Windows 10) and got this error:

java.lang.IncompatibleClassChangeError: Method 'com.intellij.openapi.roots.libraries.LibraryTable com.intellij.openapi.roots.impl.libraries.ProjectLibraryTable.getInstance(com.intellij.openapi.project.Project)' must be InterfaceMethodref constant

So, does anyone know the solution to this or has experienced this before?
