New Gradle Sync is not supported due to containing Kotlin modules using an unsupported plugin version
Faced this same error. I had to update my JVM Version in Kotlin Compiler settings.
You can find that setting here:File -> Settings -> Kotlin Compiler -> Target JVM Version
Changing to 1.8 fixed the issue.
Update Kotlin Plugin
I could be that your IDE has an older level of the Kotlin plugin.
Within Android Studio, got to File > Settings... > Kotlin and check to make sure your plugin is up to date. You may see something like this, indicating you need to update:
Also, if you run into memory issues, you may need to add org.gradle.jvmargs=-Xms1024m -Xmx4096m to the gradle.properties file.
