For a unknown reason Android Studio 3.1 Canary 3 is bugged and stopped to work, I updated gradle to 3.1-alpha03 and it stopped working, no matter if I download the project again, already downloaded Android Studio again too.

I've already checkout old versions of the project, but this message still show:

Gradle sync failed: com.android.tools.idea.gradle.project.model.AndroidModuleModel.getSelectedVariant()Lcom/android/tools/idea/gradle/project/model/ide/android/IdeVariant; (8s 806ms)

I've removed .idea folder, .gradle folder, did invalidate and restart

I don't know nothing more to do, cant run or use the IDE.

New Projects doesnt work too

To solve this issue, you have to either upgrade or downgrade your kotlin plugin

Solution 1: Upgrade Plugin

First go to Tools menu > Select Kotlin > Configure Kotlin Plugin Updates > Select one of the kotlin plugin & press download (stable or early access, i chose early access to solve this issue)

And finally change the kotlin version in build.gradle(Project:) according to the downloaded version

Solution 2: Downgrade Plugin

If your on mac then press: Command + , to open preference, then select plugin & search for kotlin & uninstall it, it will rollback to previous version: 1.1.51

On Windows machine, press Control + Alt + S to open settings dialog, then select plugins & search for kotlin & uninstall it, it will rollback to previous version: 1.1.51

Please Note: Do not uncheck kotlin in plugins else it will disable kotlin & fail to recognise kotlin file & syntax
