Unable to add a class for this project

I've tried looking into this but can't seem to find an answer. The Add > Class... option (along with other options) is greyed out.

Ran into the same problem. You most likely had used the debugger to preview the app, as the previous video had instructed. You have to use Debug > Stop Debugging for the option to add a class to be enabled.

:point_right: Did you first select a folder to which a class can be added?

I would only expect the option to be greyed out if you had something inappropriate selected when you opened the context menu.
