Google and Apple calendars are not playing friendly right now.
As alerted to us by multiple MacRumors readers, there appears to be a syncing issue with Google Calendar and Apple's Calendar that began within the past 24 hours or so. The issue prevents Google Calendar entries from appearing in Apple's Calendar app on the iPhone, iPad, Mac, and other devices.
@MacRumors have you heard anything about this? No responses from @AppleSupport or @Google but many people posting the same issue on here and forums. — Ian Laverick (@djianlaverick) August 23, 2019
The underlying cause is unknown at this time, but anecdotal customer reports across the Google support forums and Twitter suggest that the issue is on Google's end. In any case, a fix is likely in the works.

Calendar syncing is based on industry-standard iCalendar and CalDAV technologies that both Apple and Google support. But Google also has its own proprietary protocol. It's unclear which protocol is affected, based on the information provided.
It definitely sounds like a problem at Google's end, but it could also be an incompatibility at Apple's side. Maybe Google has started incorporating some new elements in the Event feed that Apple's Calendar is choking on?
Fortunately I’m off today. :D
Time wasting I know, but better than nothing.
For getting back a record of all your old events, export from Google Calendar, import as a new Calendar into iCal, & all your History will be there. When the problem is fixed by Google you can simply delete this Calendar "Record"
