App to detect keyboard shortcut assignments?

Is anyone aware of a macOS app that can detect what application or function a given keyboard shortcut is assigned to? Irradiated Software has an app called Shortcut Detective but it doesn’t seem to work that well (at least not for me). I’d love to have an app like this as sometimes one of my keyboard shortcuts will stop working and I can’t figure out why. I’ve tried looking through the macOS list of keyboard shortcuts to see if the shortcut in question has changed but that doesn’t always work. Thanks!

A recent discussion in the forums here may be of interest, but will not provide a solution I’m afraid.
