I am having the exact same issue while debugging, if I compile the app for distribution and install the IPA file manually then it's working fine on device. Hopefully this gets resolved soon as it's affecting troubleshooting issues greatly.

Same version of Xcode as the one you mentioned (14A309) from the App Store. I did not change this portion of the code and even went back to a previous version of my code using Time Machine before making any changes at all and same results. The issue seems to be when programmatically using: [self performSegueWithIdentifier:@"unwindView" sender:self]; And again only when debugging the same code but compiled for distribution will not crash and will unwind fine. I also just tried Xcode 14.0.1 RC but same issue, I might try 14.1 beta 2 and check with that version of Xcode.

It is Objective C code, there really isn't much more code to share. This one line of code triggers an unwind segue.
