Calendar app not opening

Just updated iPhone 14 Pro Max to iOS 17.0.2 and now my Calendar app will not open. The app opens on my Mac and has all of my entries, but cannot get it to open on my iPhone. Any ideas?

iPhone 14 Pro Max, iOS 17

Oct. 25, 2023, I updated my iPhone 12 Pro (i17) everything looks different, it appears as if it’s re-started, I.e. new intro to apps. My CalAlarm calendar will not open. I tap it and get a quick “blink” then nothing happens. The icon reappears on the page. Help?
