Hi, I am having a similar problem, everything worked just fine on iOS 13 and below: The debugger shows several NSLayoutConstraints stating "Unable to simultaneously satisfy constraints" and then attempts to recover by breaking one of them. I get this message in the debugger on all devices (simulator and real ones) with iOS 14 and higher but now the strange thing: On some devices I get pushed to the next view as exepted (just fine) but on the others the button I just clicked freezes and nothing happens (no crash and no message in the debugger). The viewWillAppear function of the view I want to open workes just well, I checked that. But after the viewWillAppear nothing happens. On the other devices I get displayed the view and my further action is required meaning I can use the app as expected. I really have no idea where the app is stuck in a loop or something or what is checked in the background. Has anyone an idea or suggestions what I can try?

Hi again, my App freezes (no crash, no errors) when I click on a TableViewCell which should bring me to another view (Objective C). This constraint message appears when testing on all devices so I don't think that this is the problem which causes the freezing (but could be). As I said, the viewWillAppear function of the view I want to open workes just well, I checked that. But after the viewWillAppear nothing happens, meaing the viewDidLoad isn't called. It is really strange that this problem only appears on iOS 14 and only on some devices.
