What did the troubleshooter show?

Fabler2 · Feb 28, 2023

That's what I had. Then I reset (not repair) the Mail and Calendar app and just set my email again and closed the App. Ran SFC and rebooted.
Shot in the dark, maybe running DISM /Online /Cleanup-Image /RestoreHealth first then SFC and rebooting.
I don't know what else to suggest as uninstalling/re-install didn't work.

Calendar App version 16005.14326.21344 is now also broken in the "main" track, 22621.1344.
Neither repair or reset works.

In the Event Viewer you see:

Faulting application name: HxCalendarAppImm.exe, version: 16.0.14326.21344, time stamp: 0x63ed45a6
Faulting module name: Windows.UI.Xaml.dll, version: 10.0.22621.1344, time stamp: 0x95ad35df

Just have to wait for an update I guess...

I have the same issue after the latest Windows 11 update to Buid 22621.1344 on one of my computers. The other computer has no issues.

Yes, same error in the event log here. More and more people now reporting this error, must be an issue with the latest Mail and Calendar app update.

Just got to wait for a fix.

Just received this reply from Microsoft:

Hi AlbertQX,

Sumit D - VM has replied to the question Calendar App Crashes at Startup in Windows 11: Seeking Solutions that you are following in Microsoft Community.

Microsoft is aware of the issue and very likely the issue would be fixed soon. Appreciate your patience.

This problem appears to have been caused by a very recent update of the Mail and Calendar app.
For some giving the app a 'Reset' cures the problem - for others this does not work.

Ser0o8 · Mar 1, 2023

I did reset Calendar last night and it didn't work, but today I just opened it and it finally worked. Anyways, it's gonna be replaced by One Outlook.

I'm having the same issue across three PC's, Mail works fine but the calendar stopped working so it has to be some sort of patch issue. PC's are 1 Alienware R6 on Windows 10 . One home built desktop on Windows 10, and one HP Windows 11 laptop. Spent an hour online with Microsoft but no answers from them. Decided to roll my Alienware desktop with Windows 10 back to the last restore point and Boom! Mail and calendar working again. Just prior to doing this I checked my most recent updates. It looks like something was pushed on 2/25/23 that broke the mail and calendar and the snipping tool apps. Tried the same thing on my Windows 11 laptop and no dice. Tried repairing, uninstalling and reinstalling. nothing has worked so far. Hope someone can come up with a repeatable fix. (I'd provide build numbers but I'm not near the other computers)

Bizarrely my calendar app is still working after it's brief failure and I did nothing except shut down for the night and restart in the morning on 22623.1325. It has had at least one update from the store.

Just downloaded a new version Mail and Calender App 16005.14326.21358.0 from MS Store on both computers. Still the same crash issue one of my two computers. All provided solutions including removing and re-installing the app are failing for me so far. Unfortunately, nothing would help until Microsoft fixes it. This bug was in Insiders for 2 weeks and slipped to production with the optional update. Still I do not understand why the app does work on some systems. This seems to indicate a compiling issue of the new Calender App that gives incompatible results for some processors/computer configurations.

The only workaround for me is to use Calendar on the web.

The Calendar app seems to be crashing Application Frame Host

It has to do with these switches if they're shown. If these are off everything works,

and this is how the new Outlook app looks without a switch.

Turning on the the 'try the new Outlook' to on in either Calendar or Mail they will both crash but now the switch is shown in the new Outlook app. If I turn that off in the new Outlook app then Mail and Calendar works. :woozy:

BrianInEngland · Mar 2, 2023

I don't have that switch in Mail, and it's switched off in the new Outlook app.
Calendar still crashing. I can't open Calendar to see if it has the switch

Yes - it's a total shambles.

Is this the new Outlook app from the store? The Preview one?

I have that, no switch option there either

Fabler2 · Mar 2, 2023

I guess I've been lucky as I have the Mail and Outlook apps working side by side.

Mail works fine even with the new Outlook app installed. The Try new Outlook switch is off on the MS 365 Outlook as well.
Calendar is a no-go. I've given up with that now and removed the icon from Start. I've got the Calendar widget running
