The crash occurs at line 16 of the `OnboardingController.swift` file, in the `init(onboardingController:)` method of the `OnboardingNavigationController` class.

To further investigate the issue and identify the root cause, we need to retrieve the latest breadcrumbs for this crash. Breadcrumbs provide a trail of events leading up to the crash, which can help us understand the sequence of actions that triggered the crash."
