I'm having the same error with a Cordova app on iOS 17. Weirdly the page that causes the exception doesn't even have a date picker on it. *** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer bounds contains NaN: [0 0; 320 nan].

Just had another interesting finding. I tried opening the web version of the app (which has mostly the same code) in Mobile Safari and got the same error. So it looks like there's some incompatibility with the Javascript code and WKWebView. (This is from testing on a simulated iPhone 15.)

Found that the cause of the issue was a page-change hook which used jQuery to focus and then blur a date input. When I removed this it no longer crashed.
