Catalina 10.15.4 update + Slow Contacts App performance

Ever since my Catalina 10.15.4 update a few weeks ago on my iMac (27-inch, Late 2013), my Contacts App has been incredibly slow and unresponsive. The pinwheel pops up often. I have noted the 200+ comments triggered by a previous enquiry and unless I have missed something, this remains an outstanding problem? I have the same Catalina OS on my MacBook Air 13" and the Contacts App works perfectly well

Can anyone out there offer me a solution please?

iMac 27″, macOS 10.15

macOS 10.15.4 is seven months out of date. Update it. To learn how to do that please read How to update the software on your Mac - Apple Support. It may not fix the Contacts app problem but keeping macOS updated is fundamental.
