How to fix this?

Answer 1

I went to Menu Tools > Kotlin > Configure Kotlin Plugin Updates in Android Studio. The dialog shows message A new Version 212-1.7.10-release-333-AS5457.46 is availible and an Update Button below the message. After Update and Restart the error was gone.

Answer 2

Download the newest version of Kotlin from here

then replace the Kotlin file in this directory with the one you downloaded "C:\Users\YOURUSERNAME\AppData\Roaming\Google\AndroidStudio2021.2\plugins"
