Any clues on this ?

Answer 1

Try to select File -> Invalidate Caches / Restart

I had a similar issue with Android Studio, and found this blog where the solution is posted.

I've posted this answer hoping it'll help other people who will search for this error. My Android Studio version is 0.6.1 Preview version

UPDATE: In IntelliJ 2021.3 a new feature, named Repair IDE, has been introduced which can be invoked from File -> Repair IDE or by searching for this action via Cmd + Shift + A (Mac) or Ctrl + Shift + A (Windows). Android Studio Dolphin, built on IntelliJ 2021.3, is the first to have this feature.
