The latest Mail & Calendar update from the Store restored full functionality to Calendar on both my Dev and Beta Insiders.

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.

2023-03-02T23:20:02+00:00 It was working for me with prior Beta build and Mail/Calendar version
It's still working after the update to 22624.1391 and an update to Mail/Calendar version
It is working for me on every Build, they all have the same Version 16005.14326.21358.0 including Windows 10.
The problem is easy to reproduce, just uninstalling and reinstalling the App.
Ironically that was what I did 3 days ago to fix the problem in R.P. 22621.1344, and it worked then, but not anymore. 🤷♂️
Microsoft consistency again. 🤣🤣🤣
With the same version of the App, there are reports of the failure on every Build, even if all work fine for me. 🤐🤐

2023-03-02T18:47:32+00:00 My calendar app has failed on 2 Windows 11 machines and 1 Windows 10 machine. The update you site above has not been installed on my Windows 11 machines yet. Hope they figure this out soon.
