If Shortery can't load shortcuts, here is how to fix it:
- Open the Finder
- Navigate to Applications
- Right click on the Shortcuts.app > Show Package Contents
- Navigate to Contents/Library/Helpers/Shortcuts Events.app
- Open the Shortcuts Events.app
- Open Shortery and try again
It seems like the Shortcut Events App has to be opened once before other apps can use it. Hopefully this will be fixed in a future macOS release.
