Calendar locking issue on Mac OS Sequoia 15.2

I have the same issue when trying to create new appointments. Calendar becomes unresponsive and requires a force quit. Grrrrrr. Running MacOS 15.2 on 2019 Mac Book Pro with 2.4 GHz Quad-Core Intel Core i5 CPU.

UPDATE: Sorry…no resolution. I spent hours on the phone with second-tier Apple support. We tested lots of different troubleshooting steps without success.

• Started in safe mode - no change
• Reinstalled OS 15.2 - no change.
• Removed associated LaunchAgents and LaunchDaemons - no change
• Exported calendars, then deleted them from Calendar, then restarted - no change
• Creating a new user account - Calendar does not freeze while editing in a new user account. But I cannot begin to imagine the work involved in moving everything from my current account to a new one.

Apple support team seems quite puzzled by this bug. It definitely coincides with OS update to Sequoia 15.2. Calendar is not a stand-alone app and cannot be removed and reinstalled. Support tech escalated the case and sent process log to “engineers”. Presently waiting for callback.

I have exactly the same experience. I left it for a couple of weeks expecting a fix to roll out. Now, I am getting frustrated. There do not seem to be any ideas out there.

I don't have a solution, but you can work around the issue by logging in to your iCloud calendar if you are primarily using it.
