Android Studio Gradle Sync: "Unable to load class…"

  android, android-studio, gradle, intellij-idea, java

I seem to be having an intermittent issue with Android Studio upon carrying out a Gradle Sync.

I am running Android Studio 4.1.3 with Gradle 6.8.3 on Windows. Changing the Gradle version seems to make no difference.

In the Sync output window, the following appears:

Unable to load class 'org.jetbrains.kotlin.gradle.KotlinDslScriptModelProvider'. This is an unexpected error. Please file a bug containing the idea.log file.

Pressing the Gradle Sync button multiple times sometimes causes the class name to change, I have noticed the following class names appear:

  • org.jetbrains.kotlin.noarg.ide.NoArgModel
  • org.jetbrains.kotlin.gradle.KotlinMPPGradleModel
  • org.jetbrains.kotlin.samWithReceiver.ide.SamWithReceiverModel
  • org.jetbrains.kotlin.allopen.ide.AllOpenModel
  • org.jetbrains.kotlin.gradle.KotlinGradleModel

I have attempted multiple things to attempt to rectify this, including attempting to completely re-install Android Studio.

I have included the last sync from the "idea.log" file.

Many Thanks.
