If you add --skip-install to the create-turbo command and then attempt the yarn install inside the repository do you still get an error?

Also, are you expecting a Yarn v1 or a Yarn v3 repository to be created?

This was a miss on our part - this example is missing "private": true, which yarn 1 requires in order to use workspaces.
