Build problem with Next 12 on Vercel

[antoninbeaufort]

Describe the bug
Sorry for my English I'm french :/
When upgrading from Next 11.1.2 to Next 12 this plugin seems to break on Vercel build :
[Error: ENOENT: no such file or directory, lstat '/vercel/path0/virtual:windi.css']

To Reproduce
Steps to reproduce the behavior:

1. Create a Next 12 project, implement windicss-webpack-plugin using

next.config.js

webpack(config) {
    config.plugins.push(new WindiCSSWebpackPlugin())
    return config
  },

in module.exports and
import 'windi.css'in _app.js
2. Deploy it to Vercel
3. See error

Expected behavior
No build error
