mac contacts app has stopped working
Is anybody else having problems with the Mac Contacts App? Since the last Big Sur update, Contacts has stopped working. It loads, as in I see the top menu bar, but no screen appears. I've re-loaded Big Sur, the same result. Techy bit: 2013 MacBook Pro running Big Sur 11.1 Any help would be much appreciated.
MacBook Pro 13″, macOS 11.1
