Calendar crashes after update to iOS 15.1

Hi,

Several days ago I updated my iPhone 12 to latest iOS 15.1 and what right after the update my Calendar app started freezing and sometimes crashing.

After multiple attempts to solve the issue by the Apple support the problem is still there.

Following suggestion of the apple advisors I did the following:

hard restart (+,-, side button)
reseting all setting
deleting all data and restore from iCloud back up
deleting the Calendar app and reinstaling from App Store

The problem was gone only when I restored my iPhone via finder on my MacBook Pro.

However, right after I restored my iPhone from iCloud backup the problem was back again.

During last call with Apple, the advisor suggested that perhaps screen of my iPhone is somehow damaged, which honestly makes no sense as all other apps work just fine.

It all looks like the bug appeared in my iCloud backup after latest update and it seems Apple is not capable of resolving the issue (all in all I was in contact with apple support 5 times during this week)

Would be great to know if you had similar issue and if it was resolved other than restoring the iPhone from the scratch.

Cheers,

Cezary

iPhone 12

I was having the same issue for weeks on my 11 Pro Max and now the 13 Pro Max.

I was just able to fix it by clicking on the “Calendars” after it loaded and then unselecting ‘Siri Siggested’, ‘Birthdays’, ‘Calendar’, ‘Work’ and ‘Home’ calendars. I left the exchange one selected then clicking “done”. It immediately fixed the issue but I verified by closing the app then reloading and selecting the calendars I want. The interface looks a little different but now it loads fine.

maybe this’ll help others fix their crashing and stuck/slowcalendar app.

Same here. All this $$ for apple technology, and they can’t get IOS UPDATES accurate. They fix one thing & damage something else that’s critical.

No option correct, as hard reset doesn’t work, had to restore back to factory settings. Now the real work starts reorganizing the apps, adding their user names and passwords etc. Their iOS errors are time consuming and damaged 4 days of my calls scheduling locking me out. Hope they get their act together, as I’m exploring more reliable backups.

I'm having the same problem what do even more so. Even when I use my Mac and go to iCloud.com, login, and click on calendar, events that I have created on either my iPhone, iPad or Mac do not show up in iCloud calendar. If I create an event on the iCloud calendar via Safari the event sometimes shows up on my Mac's calendar app. I've had two support calls with Apple tech and awaiting a call back on Thursday. I'm also pretty sure this started working since the latest iOS update but it seems to be also with the iCloud calendar server as I get errors when trying to open calendar on iCloud.com.

i have the same problem after downloading 15.1.1 on iPhone 13 and also have Exchange porting into my calendar. My calendar is basically unusable at this point & I need it for my job in the day to day. If they don’t fix it soon I may have to switch to android.

This completely fixed the issue for me.
