Kotlin Standard Functions Unresolved Reference Android Studio

Suddenly all of the projects in Android Studio are getting this unresolved reference for kotlin standard functions like .let , .apply , listOf & mutableListOf and also missing coroutine scope functions like .launch

enter image description here

Android Studio Version : 2020.3.1

Things I've tried

  • Created a new project
  • Deleted App build folder & library build folder
  • Cleaned Project , Rebuild Project & Invalidate Caches & Restart
  • Deleted .idea folder and rebuilt project

App builds and runs fine on emulator , just the IDE gives this error in every project


I have solved the problem by changing the Gradle version.

change the gradle-wrapper.properties
