ios - iOS 应用程序在控制台显示时卡在启动屏幕：尝试为已有的场景句柄创建面包屑操作？

Question

1.从TestFlight下载我的应用后点击，或者直接从Xcode运行，应用卡在启动界面，无法继续。

2.与macOS连接时，从Console中我们可以看到SpringBoard过程中可能出现的一些相关错误：

Attempting to create a breadcrumb action for a scene handle which already has one (sceneID:#myAppName#-default). Are you trying to active an app that's already active?
...
[Main] dispatch event:
<SBMainTransitionSwitcherModifierEvent: 0x2837d7dc0; type: MainTransition; transitionID: xxx; phase: Complete; animated: YES; fromAppLayout: 0x0; toAppLayout: <SBAppLayout: 0x281500e80; primary: #myAppName#; environment: main>; fromEnvironmentMode: home-screen; toEnvironmentMode: application; pendingTermination: {(
)}>

当应用程序可以正常启动时，该日志中的“pendingTermination: {()}”不会出现。现在我们在我的应用程序进程中看不到任何日志。

3.然后当我锁定屏幕并解锁时，iPhone只显示黑色背景，我不能像往常一样使用我的iPhone。这是控制台中的日志：

3.1 锁屏：

[sceneID:#myAppName#-default] Setting deactivation reasons to: 'appSwitcher, systemAnimation' for reason: updateAllScenesForBand - Assertion added.

Calculated state for application<#myAppName#>: none (role: UserInteractiveNonFocal)

3.2 解锁屏幕：

4.重新启动我的iPhone后，一切又恢复正常。

这个bug最近出现了好几次，但我之前没有遇到过这种问题。

它是 SpringBoard 中的错误吗？或者它是我的应用程序中的一个错误，我该怎么做才能修复它？

谢谢。
