body: <p>I am trying to run a react project in my Windows environment but It's throwing the following error. Before, this project worked on Ubuntu with the same things. It started to happen after I changed the OS. How can I fix this?</p>
  <p>I am just running <strong>npm start</strong> command.</p>
  <pre><code>
  &gt; REACT_APP_VERSION=$npm_package_version react-scripts -r @cypress/instrument-cra start
