I have been using an App (Visual Studio Code) on Mac OS X for several months now. Somehow I've gotten the app into an unusable state on Mac OS X. I uninstalled it and reinstalled it. However, that did not work. It looks like my user settings and preferences persisted though. Which means that there are some files or settings somewhere on Mac OS X.
Where do those files / settings get stored? I would like to remove them and start from scratch and see if that fixes my issue.
