title: VS-Code won't starte because of missing /dev/fd/3
body: <p>I'm using vs-code installed via snap on openSUSE Leap 15.2
  Until rebooting my machine today everything was fine.
  Now, when I try to start it, I get the following  error:</p>
  <pre><code>No protocol specified
  [7065:1118/173715.565235:ERROR:browser_main_loop.cc(1473)] Unable to open X display.
  The futex facility returned an unexpected error code.
  /dev/fd/3: No such file or directory
  Server response:
  </code></pre>
  <p>I tried rebooting, reinstalling it, and deleting the ~/.config/Code folder, with no success.
  Currently I have version 1.51.1 installed.</p>
  <p>Edit:
  I'm not root and I'm locally on a machine with GUI (KDE). Trying to start code as root gives the same error. Other graphical applications are working fine (like the browser I'm writing this from)</p>
