Error on build with brand new Vue project

[Wozza365]

Same result on 3 separate machines, Windows 10 + Node 16.10.0 / 16.13.0 / 16.15.0

Ran npm init vitebook
Go through the steps for a Vue project
Run npm install
Add one sample story (literally just one element in a .vue template
Then run npm vitebook:build

Build then fails with the following error:

Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only file and data URLs are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

Has anyone had this and been able to resolve it? We've tried on 3 separate machines and all return this error. Not much helpful info on this either.

And vitebook:dev command runs and loads the site/story as expected.
