仅在 iOS 16 上出现致命异常 NSInternalInconsistencyException

Question

我被这个 Firebase 崩溃报告困住了

CoreAutoLayout NSISLinExpReplaceVarWithVarPlusDelta

。在阅读堆栈跟踪时，我似乎突然在后台线程上执行自动布局更新。但我无法找出它在整个项目中的位置。顺便说一句，报告说100%来自iOS 16，我想知道iOS 16上的自动布局是否有任何更新。我在模拟器和真实设备上都尝试过，但仍然无法重现这个错误。有谁知道如何查找/修复此错误？预先感谢。

我也遇到了同样的问题，打开Xcode的Main Thread Checker一直无法追踪到具体位置，但是网上每天都有这个崩溃反馈。目前我检查iOS 16.0以上系统的设备均出现，需要官方帮我们解决这个棘手的问题
