I have just updated Android studio 2.2.2 to 2.3 from the canary channel. After downloading completed and applying path file, the android studio is restarting.
But after restarting android studio I am getting below error with dialog:
Cannot load project:
com.intellij.diagnostic.PluginException: Could not initialize class
Disable the Kotlin plugin and restart Android Studio. I had the same error even after I updated the plugin. So disabling seems to be the solution for now -- unless you're using Kotlin, I guess.
I'm sure there will be an updated version of the plugin soon.
