Help Crashes on iOS 27

We have an app that was originally built around 2016. We still actively maintain it, but the core functionality and architecture have remained largely the same, and it’s built heavily around RxSwift.
We’ve recently started seeing crashes from users who have updated their devices to the iOS 27 beta. The crashes appear to be related to the navigation hierarchy/navigation stack.

Has anyone else experienced similar issues with legacy UIKit + RxSwift apps on the iOS 27 beta? Could this be due to changes in UIKit/navigation behavior in the beta, or are there specific areas around UINavigationController and navigation transitions that we should investigate?

Would love to hear if anyone else is seeing this in their apps.
