The latest Mail & Calendar update from the Store restored full functionality to Calendar on both my Dev and Beta Insiders.
Windows Calendar app crashing
The Windows Calendar app is crashing on launch, it was updated through the Store to version 16005.14326.21344.0 a few days ago.
Screenshot of the error log from Reliability monitor.
Windows 11 Release Preview 22621.1343.
Already tried to reset the Calendar app, and also uninstalled/re-installed WINDOWS COMMUNICATION APPS from the Store.

2023-03-02T05:16:24+00:00 Still crashing after an app update this morning. To be honest I can't be bothered to reset the Mail apps AGAIN to see if that fixes it.
Mail works and I have the Calendar widget running, maybe one day the Calendar app will be fixed, maybe not.
I never use that calendar anyway; I just tried it out when I saw users reporting that it was broken.
It is ironic that it works on all my machines, even if I never actually use it or need it. π€£π€£π€£π€£

2023-03-02T03:14:50+00:00 New error log after they updated the Version to .21358.0, now it just hangs instead of crashing. π€£π΅βπ«
Edit:
After a reboot it started working again. This was a test on Dev Build. ππ€·ββοΈ
I uninstalled the App and reinstalled it from the store at 19:23 on March 1, 2023

2023-03-02T02:24:46+00:00 Seeing the same issue. I have Windows 10 though. App is crashing after a recent update.
I have windows 10 too and it tries to open and the crashes immediately.
Windows 10 received the same Version 16005.14326.21344.0 as Windows 11.
Still unclear why some machines fail while other do not have the problem.
I received the same updates on all my machines, and they are still working correctly.
I had the failure only on one machine and it was fixed when I tried Repair and Reset of Mail and Calendar App.
That is also strange, because now I can reproduce the problem on every machine just by doing exactly the same thing. π€£π€£π€·ββοΈ
No idea about what changed in the last 2 days to produce the problem.
Now I can reproduce the error on both Versions of the App 16005.14326.21344.0 and 16005.14326.21358.0.
I have not seen any reply to the FBH reports from MS.
They should give an explanation on the reason for the failure which looks the same for both versions of the Mail and Calendar App. π€
Edit:
The second version just updated on Build 22621.1344 and also Windows 10, now all machines have the same version. ππ€·ββοΈ
16005.14326.21358.0
Same version in Windows 10:
