title: Unity hub error opening unity version 2019
body: <p>After installing unity hub, I had Unity 2017 already installed. Then I downloaded Unity 2019 from the Unity Hub without any extra build support.</p>
  
  <p>Then I made a new project in unity 2019 from the hub. The project does not start. When I open it manually I get the following error message:</p>
  
  <blockquote>
    <p>Project does not exist: /Users/user/Desktop</p>
  </blockquote>
  
  <p>I tried restarting my laptop but the same problem occurs.</p>
  
  <p>What I notice when I make a new project from unity hub of unity 2019
  that unity launches in the dock for one millisecond then it disappears. <strong><em>Note: I am using a mac</em></strong></p>
  
  <p>What I think is that unity is opening then it closes instantly.</p>
