title: Postman launches with a blank screen
body: <p>This is now the third or fourth time that this has happened in the last couple of weeks: When I launch Postman all I get is a blank screen:</p>

  <p>The only way to get around this that I have found is to reboot my workstation, which is of course a PITA. </p>
  
  <p>I am using Ubuntu 18.04.4 LTS, 7.20.0.</p>
  
  <p>Any fixes, workarounds etc are welcomed. </p>
