Issue description or question

Seems that Quokka crashes as soon as Webstorm starts. It isn't breaks or crashes anything but shows error flashing light at the bottom bar and doesn't show Quokka's icon on Toolbar.

Full traceback:

We couldn't duplicate this problem, but we've updated the IntelliJ extension to perform an additional check before some of our application logic that should fix this for you. Please download the latest version of the Quokka IntelliJ v1.0.164. So that you can start WebStorm, you can remove Quokka by going to your plugins directory (~/Library/Application Support/<PRODUCT><VERSION>) and deleting the quokka-intellij folder.

Thanks, Quokka IntelliJ v1.0.165 works fine! 👍
