title: APP launch error: Service could not initialize: 18E226: xpcproxy + 11291
body: <p>I've built an App in Xcode. I've signed it with a valid Developer ID certificate. Notarized and released the app via Archive function in XCode. And the app launches fine on some MacBooks.
  But on another launch fails with error</p>
  <blockquote>
  <p>The application %name% can't be opened.</p>

  <p>I've checked the system.log and it says</p>

  <p>The app is very simple. It is just a Notification center widget (APP Type XPC!). It receives data from remote URL and displays it via NCWidgetListViewController.</p>
  <p>The source code could be found on <a href="https://github.com/obukhow/OggettoLunchMac/" rel="nofollow noreferrer">github</a></p>
  <p>As I mentioned the problem exists only on some machines. The rate is about 50/50. On all machines app installation from Anywhere is allowed. spctl-master is disabled. Permissions for files are correct.</p>
