The issue you are facing:
On my macOS and iPadOS devices, CalDAV syncing for calendar and reminders doesn‘t work as expected. When I create and edit events/reminders on those devices, they get properly pushed to the server. When I edit/remove events with other clients or using the web interface, the changes aren‘t fetched by the Calendar/Reminders app and sort of get stuck on iPadOS/macOS. Even when force-refreshing calendars (Command+R on macOS, pull-to-refresh on iPadOS) it does not update (for Reminders, there is no manual way to update).
If I remove the account and re-add it, the data is fetched properly. It‘s not a good workaround however to do this every so often.
Is this the first time you’ve seen this error? (Y/N): Yes.
Steps to replicate it:
Setup Calendar/Reminders sync on an iPad/Mac.
Delete an already existing event using the web interface.
Open the calendar app on the Mac/iPad and refresh. The deleted event is still there.

Output after refreshing:
On macOS 12.6 “Montery” with Nextcloud version 26.0.2 on a DirectAdmin server I have the same issue. Also on iOS (quite recent, I don’t have the version available now).
When I start the Reminders app on macOS I get serveral log entries:
