Hello,
I have just testing caldav on my hassio installation running 0.109.
Caldav server access works when used from eg calendar app on macos.
However, in ha it doesn’t. The debug log shows:
2020-04-30 12:27:27 ERROR (MainThread) [homeassistant.components.calendar] caldav: Error on device update!

vevent = event.instance.vevent
AttributeError: 'NoneType' object has no attribute 'vevent'
I have events in the calendar… So I am not sure where to search.
I have put the logger to debug level, not more detail.
Clues welcome!
