Google Calendar Sync hangs infinitely on one specific calendar

Description: I am experiencing an issue where the Google Calendar synchronization has stopped working for one of my calendars.

Details & Observations:

  • The Issue: When attempting to sync, the loading spinner spins indefinitely, and the synchronization never completes.

  • Other Calendars Work: I have two other Google Calendars linked to my account, and both of them sync perfectly fine and without any delay.

  • Hypothesis: I suspect there is a specific entry, recurring event structure, or corrupted event in this particular calendar that the parser cannot process, causing the sync process to hang.

  • Impact: This is my primary and most important calendar (containing private appointments). I rely heavily on seeing these events in Intervals.icu to plan my training sessions around my daily life.

I am highly technical and more than happy to assist with debugging, providing specific event data, or sharing logs if that helps to pinpoint the issue.

Thank you in advance for your help!
