I’m a bit confused. Kotlin version 1.4.0 is not released (as far as I know). Are you using the RC build? In that case you might want to also use the RC build for the kotlin plugin. IDEA > tools > kotlin > konfigure kotlin plugin update. You can set the update channel to “Early Access Preview 1.4.x”

If that does not help you should create an issue here: https://kotl.in/issue

The discussion you linked leads to an old issue in a 1.0.4 eap release that has been fixed. Maybe it’s a regression error or something new that looks the same. In any case you should link to https://youtrack.jetbrains.com/issue/KT-13371 if you create a new issue.

Kotlin just releas the stable1.4.0 just few days ago
I just updated to find whether the latest release version works
please see the page:Release Kotlin 1.4.0 · JetBrains/kotlin · GitHub :grinning:

Mmmm… I haven’t seen that one. But I’m guessing the 1.4.0 release not yet finished. Otherwise there would have been an announcement about it. It’s probably still missing the release of a few libraries and tools.
Also for anyone else interested here is the new youtrack issue: https://youtrack.jetbrains.com/issue/KT-41131
