I had the same problem, the @y.bedrov's suggestion helps me.

The issue is that the Classpath is empty (under Project Structure -> Platform Settings -> SDKs -> <choose active SDK> -> Classpath)

To fix this, you can recreate the SDK:

  1. Project Structure -> Platform SDKs -> <choose active SDK> -> "-"
  2. Project Structure -> Platform SDKs -> "+" -> <choose target SDK location>

This was definitely some IntelliJ peoblem for me. I could solve the issue by stupidly deleting the "problematic" class and creating it again:

  • Delete class and imports that refer to it in project
  • Create the same class and adding imports

What generally people also suggest when having similar problem (but didn't help in my case):

  • Restart IDE (File -> Invalidate caches... )
  • Check Platform SDKs as mentioned in another answer here
  • IntelliJ -> PReferances -> Build, Execution, Deployment -> Make sure that Kotlin Compiler and Java Compiler match in versions.
