title: Why is Gluon SceneBuilder Not Working Correctly
body: <p>I have been doing a project and on IntelliJ with SceneBuilder 9.0.1. Yesterday, did a mini project on NetBeans 8 after 12 wasn't starting a new project for some reason. Once I was done on closing everything and opening my IntelliJ project, the fxml documents were not opening with the SceneBuilder.
  With this problem, the following things need to be noted:</p>
  <ol>
  <li>I'm using version 9.0.1 though v15 did had the same issue as well,</li>
  <li>The fxml was not opening in NetBeans either,</li>
  <li>The reinstalling would open a blank project and open some recent files, but some would not open. After closing it, It would not open again,</li>
  <li>Checking the task manager after trying to open it. It would be visible as a background process taking quite some RAM. Sometimes it would only appear after I close IntelliJ</li>
  </ol>
  <p>A sample of one of the fxml files is as below:</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
