When I try to doubleclick-execute a .desktop file it opens up the GNOME Games launcher and does nothing else. Even if i try to reset the opening application by right clicking and editing the properties, the default application still remains the games one (Icons don't work too).
Executing the file via terminal, using
gtk-launch filename.desktop, works fine.
Is there a configuration file that I should edit or something more to reset?
I'm working on Ubuntu 19.04 with GNOME 3.32.1
