### Is this a bug report?

Yes


<!--
  If you answered "Yes":

    Please note that your issue will be fixed much faster if you spend about
    half an hour preparing it, including the exact reproduction steps and a demo.

    If you're in a hurry or don't feel confident, it's fine to report bugs with
    less details, but this makes it less likely they'll get fixed soon.

    In either case, please fill as many fields below as you can.

  If you answered "No":

    If this is a question or a discussion, you may delete this template and write in a free form.
    Note that we don't provide help for webpack questions after ejecting.

### Did you try recovering your dependencies?

<!--
  Your module tree might be corrupted, and that might be causing the issues.
  Let's try to recover it. First, delete these files and folders in your project:

    * node_modules
    * package-lock.json
    * yarn.lock

  Then you need to decide which package manager you prefer to use.
  We support both npm (https://npmjs.com) and yarn (http://yarnpkg.com/).
  However, **they can't be used together in one project** so you need to pick one.

  If you decided to use npm, run this in your project directory:

    npm install -g npm@latest
    npm install

  This should fix your project.

  If you decided to use yarn, update it first (https://yarnpkg.com/en/docs/install).
  Then run in your project directory:

    yarn

  This should fix your project.

  Importantly, **if you decided to use yarn, you should never run `npm install` in the project**.
  For example, yarn users should run `yarn add <library>` instead of `npm install <library>`.
  Otherwise your project will break again.

  Have you done all these steps and still see the issue?
  Please paste the output of `npm --version` and/or `yarn --version` to confirm.
-->

Yes
