CalenderAgent constantly using 60% CPU

I’m just curious if anybody else sees their Catalina constantly devote 60% CPU to the CalendarAgent task.

All my work is on Google so I sync to Google calendar. I also use iCloud Calendar for my personal stuff. is running all the time, but is backgrounded and barely uses a cycle here and there. But the ominous “CalendarAgent” always seems to chewing through about 60% CPU (on a quad-core 13" MBP) even when the rest of the box is just idling. It’s just 15% of the Mac’s processing capacity, but it still seems quite excessive. Anybody else? Any ideas? Setting up Calendar from scratch did nothing about it. Not 100% sure, but don’t think it was like this on Mojave.
