SUMMARY Discover crashed when closed the app on wayland session. I opened Discover app & browsed "settings section etc", then the app is not responding with message "Discover is not responding". Then I closed the app and opened it again, then again browsed the settings section, featured applications etc. After that when I closed the Discover application using close button on top right corner then a notification came that the discover app is crashed.
