I just reviewed the change log and see that V4 just went live on 2021.11.30, so I’m guessing this is just a case of the starter scripts needing to be tweaked for V4.
The create-strapi-app script has a minor issue (@strapi/design-system needs to be installed manually), but other than that, everything seems to be working fine!
I’m going to flag this closed on the assumption that the starter scripts will get updated soon enough.
