I have a textField (for doing searches in map) placed on top of a MapView using ZStack. When I type on the textField in XCode 11 on Simulator, there was no problem. Everything worked. Then in XCode 12, the app started crashing the minute I tapped on 'Enter' on the keyboard and the keyboard went away. Aside from the error you mentioned, I also get: "[LayoutConstraints] Unable to simultaneously satisfy constraints."

I can't add a bank account anymore. Apple seems to have removed the link.
