Three-finger lookup is not working after updating to MacOS Sonoma 14.4.1

Look up words on Mac

Excerpt from above link

1. On your Mac, in an app or webpage, or in a photo or image, Control-click a word or phrase (in some apps you may need to select it first).
2. Or you can tap the trackpad with three fingers (if the gesture is selected in Trackpad settings). If your trackpad supports force click, you can set the Look Up gesture to use that instead of a tap.
3. Choose Look Up from the shortcut menu.
4. In the Look Up window, do any of the following:

• • See the full definition: Click the “more” link at the end of the short definition.
  • See the word in the Dictionary app: Click Open in Dictionary. To learn more about Dictionary, see the Dictionary User Guide.
  • See more information: Click a category—such as Siri Knowledge—if available at the bottom of the Look Up window, or swipe left or right on the trackpad.
  • Change dictionary sources in the Dictionary app: Click Configure Dictionaries to open the Dictionary settings window. Select or deselect sources. You can set options for a selected source, such as how to display pronunciations or which language of Wikipedia to search.

You can use a three-finger tap when the pointer hovers above a selected or unselected word. Alternatively, you can use ctrl+cmd+D. The top-to-bottom order of the dictionary results from this form of lookup will be the top-to-bottom order of your dictionary selection order in the Apple Dictionary application's Settings.

You will need to practice touching the trackpad with all three fingers concurrently. This may also require adjustments in trackpad sensitivity.
