Glitches with adding to block lists/white lists

The app keeps crashing every time i try and add a site or an app from Information and Reading, Productivity and Finance, Other, or search from the search bar. THIS APPLE SCREEN HAS CRASHED pops up trying to do any of these.

There’s a suggestion to search to add apps following a 16.4 iOS update - is this the long term solution (not that this works, the search functions not working after all).

IOS up to date and so is the app on the latest version (30th Sept).
