Flutter 颤振1.22.0 IOS应用程序连接丢失问题

我已经从较旧的版本迁移到了flatter1.22.0。当我试图在IOS模拟器中运行应用程序时，它只是打开应用程序并崩溃，并说连接丢失。但是在Android Studio中，它仍然显示它正在运行，我的意思是运行和调试按钮被禁用，但停止按钮处于活动状态

颤振运行--verbose输出为

下面的日志我看到在结束后，什么也没有发生

每当我启动IOS模拟器时，它都会给我“聚光灯意外退出。”错误。请参见下面的屏幕截图。不确定是否与此问题有关。。。

您仍在使用旧版本的颤振。v1.22.2本周发布。尝试使用

flatterupgrade--force

升级flatter你能分享

flatter run--verbose

结果吗？谢谢，我已经添加了问题中输出的链接。谢谢。我更新到了最新的一个，但它仍然给出相同的错误。
