After updating to iOS 18 the calendar freezes when I try to edit it. I have tried to restart it several times, but it doesn’t help. Any suggestions? Hoping for a quick trouble fix update.

iPad Pro (4th generation)
Same issue with my iPad Pro M4 13" as well as my iPhone 15 Pro Max. Have tried offloading and reloading calendar from storage, uninstalling and reinstalling calendar and showing only our shared family calendar with no tasks, changing from sync all past events to just the last two weeks, as well as multiple forced and non-forced restarts on both devices, signing out and back into iCloud on the iPad, unpairing and repairing my Apple Ultra v2 watch to the iPhone. When try to add any event to the calendar on the iPad the application freezes and then on restarting the app the calendar is blank requiring a reboot. Very similar behavior on the iPhone except for a few times successfully added a test event.
Also calendar app is chewing up my battery on both devices with background activity to the point where my iPad is shut down hoping 18.0.1 solves this issue soon. Soon after the update the phone gave a suspended charging temperature alert but this has improved. After shutting down the iPad a few days ago the phone continued to show that the majority of battery use is calendar background activity but battery drain seemed to be approaching normal behavior but as I type the phone is warm at 47% charge down from 90% with overnight charge after only 3 1/2 hours use showing calendar at 66% background activity/18h 10m. Traveling next week and would be nice to see this resolved prior to the trip.
Prior to shutting down the iPad was also having an issue with mail syncing between iPad & iPhone from my exchange account but secondary battery drain was playing with settings from push to fetch and since returning to push improved but still had to sort through emails on the iPad after deleted them from the iPhone before I shut the iPad down.
Also have iMac Pro 2017 and iMac M3 updated same day as did iOS 18 to Sequoia which thankfully has been painless.
I wasn’t able to try that because the iPad froze totally, I couldn’t do anything. I had to connect it to my computer to reset it. Hope you stopped the problem.
Short lived victory. iPhone shared family calendar still functioning normally but crashing again on iPad when try to add event.
Spoke too soon. Calendar app on iOS 18.0 on iPhone 14 Pro worked only momentarily. It has returned to its lengthy, 10-15 minute delay when saving/modifying any data. Too painful. I give up.
I have had exactly the same experience as you. I do not have an exchange account however. Sync issues are also occurring with the Message app. I hope Apple gets to the bottom of this soon.
On the iPad, try to do a hard restart, and then try to delete the calendar.

Thank you! That worked like a charm.
