title: ERROR MODULE NOT FOUND whenever I try to run 'npm run dev' using Next.js
body: <p>Whenever I run <code>npm run dev</code> I get this error.</p>
  <p>I've tried to delete <code>node_modules</code> and reinstall it using <code>npm install</code> but that didn't work. Then I tried to delete both <code>node_modules</code> and <code>package-lock.json</code> and reinstall them, that didn't work. I even tried upgrading Node to the latest version, but I'm still getting this issue.</p>
  <p>I appreciate any help I get. Thank you in advance.</p>
