title: Cannot convert project: C:\workspace_IntelliJ\Main\new-webapp\.idea\workspace.xml: Error on line 1: Content is not allowed in prolog

  <blockquote>
    <p>Cannot convert project: C:\workspace_IntelliJ\Main\new-webapp.idea\workspace.xml: Error on line 1: Content is not allowed in prolog.</p>
  </blockquote>
  
  <p>What does this error mean? I have checked my workspace.xml. Whenever I try to open it in an editor it displays the following (I believe it's broken):</p>
  
  <pre><code>nulnulnul
