### 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.
    You can find webpack docs at https://webpack.js.org/.

### 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

### Environment

<!--
  To help identify if a problem is specific to a platform, browser, or module version, information about your environment is required.
  This enables the maintainers quickly reproduce the issue and give feedback.

  Run the following command in your React app's folder in terminal.
  Note: The result is copied to your clipboard directly.

  `npx create-react-app --info`

  Paste the output of the command in the section below.
-->

just says it's missing app name

### Steps to Reproduce

<!--
  How would you describe your issue to someone who doesn’t know you or your project?
  Try to write a sequence of steps that anybody can repeat to see the issue.
-->

It's definitely something in my project (upgraded from latest 1.x), because a brand new app works. when I first start the development servers, it has the following html:

```
<body>
    <div id="root"></div>

    <!--
      This HTML file is a template.
      If you open it directly in the browser, you will see an empty page.

      You can add webfonts, meta tags, or analytics to this file.
      The build step will place the bundled scripts into the <body> tag.

      To begin the development, run `npm start` or `yarn start`.
      To create a production bundle, use `npm run build` or `yarn build`.
    -->
    
    <script src="https://www.google.com/recaptcha/api.js?render=explicit" async defer></script>
    <script src="/static/js/bundle.js"></script>
    <script src="/static/js/0.chunk.js"></script>
    <script src="/static/js/main.chunk.js"></script>
</body>
```

The Page comes up blank and react-dev-tools (chrome extension) says `this page is not using react`
It's almost like the JS is never executed

But as soon as I refresh the page, the page works as expected with the following html served **(notice chunk 0 is now chunk 1)**:

```
<body>
    <div id="root"></div>

    <!--
      This HTML file is a template.
      If you open it directly in the browser, you will see an empty page.

      You can add webfonts, meta tags, or analytics to this file.
      The build step will place the bundled scripts into the <body> tag.

      To begin the development, run `npm start` or `yarn start`.
      To create a production bundle, use `npm run build` or `yarn build`.
    -->
    
    <script src="https://www.google.com/recaptcha/api.js?render=explicit" async defer></script>
    <script src="/static/js/bundle.js"></script>
    <script src="/static/js/1.chunk.js"></script>
    <script src="/static/js/main.chunk.js"></script>
</body>
```

### Expected Behavior

<!--
  How did you expect the tool to behave?
  It’s fine if you’re not sure your understanding is correct.
  Just write down what you thought would happen.
-->

It should just load the right chunk the first time


### Actual Behavior

<!--
  Did something go wrong?
  Is something broken, or not behaving as you expected?
  Please attach screenshots if possible! They are extremely helpful for diagnosing issues.
-->

It doesn't execute react on the first load


### Reproducible Demo

<!--
  If you can, please share a project that reproduces the issue.
  This is the single most effective way to get an issue fixed soon.

  There are two ways to do it:

    * Create a new app and try to reproduce the issue in it.
      This is useful if you roughly know where the problem is, or can’t share the real code.

    * Or, copy your app and remove things until you’re left with the minimal reproducible demo.
      This is useful for finding the root cause. You may then optionally create a new project.

  This is a good guide to creating bug demos: https://stackoverflow.com/help/mcve
  Once you’re done, push the project to GitHub and paste the link to it below:
-->

Very confidential app. will try to bring it down to an MVP I can share. in the mean time I would love at least a direction to look in. there are absolutely zero errors in the console

Similar to [#4788](https://github.com/facebook/create-react-app/issues/4788) and [#4757](https://github.com/facebook/create-react-app/issues/4757)

<!--
  What happens if you skip this step?
  
  We will try to help you, but in many cases it is impossible because crucial
  information is missing. In that case we'll tag an issue as having a low priority,
  and eventually close it if there is no clear direction.
  
  We still appreciate the report though, as eventually somebody else might
  create a reproducible example for it.

  Thanks for helping us help you!
