We were trying to test our app on older versions of iOS and to our surprise it crashed on startup.
I tried the starter app and it seems to be crashing too, we original had an iPhone on iOS 11 and that is where we found the issue. Then tried the simulator to test other versions.
It affects:
iOS 11.x
iOS 12.x
iOS 13.x
iOS 14.x is working
The debugger is complaining about WKWebViewConfiguration()
Here is a screenshot
