Shortcuts crashing

When I click on a Shortcut link like this one posted by @Aaron_Antcliff , Shortcuts opens, then crashes. In fact, it won’t open and immediately crashes, no fault of Aaron’s of course. Any ideas?
iPad Pro 10.5”, iOS 12.1.4

I use Fredrico Viticci’s Siri Shortcut that sets a timer on my iPhone, puts it into Do Not Disturb, and starts a timer in Toggl so I can keep track of the number of hours in any given context. You can find it here :slight_smile:
