Can't walk dependency graph: cannot find module

I want to make use of the cypress markdown preprocessor.
After installing it with npm:
npm i -D cypress-markdown-preprocessor

and configured the plugin:
/ cypress.config.js
const { defineConfig } = require('cypress')
const mdPreprocessor = require('cypress-markdown-preprocessor')

module.exports = defineConfig({
e2e: {
setupNodeEvents(on, config) {
on('file:preprocessor', mdPreprocessor)
return config
},
// use Markdown file from folder "docs" as tests
specPattern: 'docs/**/*.md',
},
})

I created a first test file, which I ran in Cypress. I got an error:
Can't walk dependency graph: Cannot find module in
node_modules@bahmutovcypress-fiddlesrcindex.js'

That is strange because I have this folder in my node_modules:
node_modules@bahmutov\cypress-fiddle\src\index.js

So, because there was only one place where I had to fill in a require, at the mdPreprocessor cypress config, I don't know what to do.

@olafgorter From what I have seen it happens in Windows machines, had no issues while doing the same on a Mac.

I tested it again on a empty project. Just a index.html with an h1 tag. Installed Cypress, installed Cypress Markdown Pre Processor. Configured the plugin:

// cypress.config.js
const { defineConfig } = require('cypress')
const mdPreprocessor = require('cypress-markdown-preprocessor')

module.exports = defineConfig({
e2e: {
setupNodeEvents(on, config) {
on('file:preprocessor', mdPreprocessor)
return config
},
// use Markdown file from folder "docs" as tests
specPattern: 'docs/**/*.md',
},
})

wrote test.md file in docs folder. open cypress. choose selected test.md files. error:
Can't walk dependency graph: Cannot find module

Do I do something wrong?
