Android Studio Start Failed when updated to 4.1

this way will work remove this files

C:\Users\YourUserName\AppData\Roaming\Google\AndroidStudioPreview4.1 Because there is no Kotlin plugin compatible with Canary 9 currently available from JetBrains, we have bundled our own Kotlin plugin with the Canary 9 update, so you don't need to manually install a Kotlin plugin see this https://developer.android.com/studio/preview/features#4.1-ki-missing-kotlin-plugin

For Ubuntu: please remove the file .local/share/google and Open android studio it will work.

For Windows, go to:
%USERPROFILE%\.AndroidStudio4.0\config\plugins\marketplace and remove the lib folder
