Endless loading of one calendar

I am just now seeing this message on NC 24. How do we go about finding the calendar in question? I’m onboarding several people that are migrating calendars from Google so I am not sure where the culprit could be.

it doesn’t really make sense to re-open a thread after SIX years.

Pls give out proper information about your system, your system environment, logs etc.

Nextcloud 24.0.6 on an in-house Ubuntu 20.04.5. The Calendar app is at 3.5.5. We use the Google Integration app for migrating Google Calendars for what it is worth. So I’m not sure if I just need to track down the offending user/calendar and figure out what is unique on the event. But with so many users and calendars, I’m not sure how to track it down.
