title: IntelliJ IDEA not showing my module/project
body: <p>Suddenly, IntelliJ IDEA is showing the following module view with a strange yellow colour in the background. I don't know how to get my module back, because it is not being shown: <img src="https://i.stack.imgur.com/sixDP.png" alt="enter image description here"></p>
  
  <p>Do you know how can I see my project folder back?</p>
  
  <p>Thanks</p>
