Inability to open build.gradle.kts caused by old version of Kotlin plugin

Which version of kotlin plugin do you use? I use the up-to-date kotlin release version and the error happens. As far as I know we don’t need to use dev version of kotlin plugin anymore, right?

1.1.50 from EAP channel works fine

you can use the latest released 1.1.x version of the Kotlin plugin for working with the code

So, this is not correct, then
