When execting npm test in Lab 7.1 on WIndows 11 with Node v16.14.0 installed I get 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 'f:'

I fixed the test by slightly changing the module loading according to your own tutorials in the chapter
Adding pathToFileURL

import { pathToFileURL } from 'url'
import { createRequire } from 'module'
import assert from 'assert'
const { resolve } = createRequire(import.meta.url)
const { default: add } = await import(pathToFileURL(resolve('.')).toString())

assert(typeof add === 'function', 'function exported')

assert(add(15, 7) + add(11, 9) === 42, 'correct function exported')

console.log('passed!')
