【问题描述】：
我只是想开始优化我的应用程序并通过 Instruments 启动它。但无论我使用哪种工具，我的应用都会在启动时立即崩溃。
当我正常运行我的应用程序时，它没有显示任何问题。此外，几天/几周前我用 Instruments 运行它，没有问题。但今天它甚至不会开始。
仪器显示以下内容（从简短的开始）
Total Samples Running Time Self Symbol Name
322 322.0ms 92.0% 0,0 Main Thread 0x1734
256 256.0ms 73.1% 0,0 start

4 4.0ms 1.1% 0,0 start_wqthread 0x1754
2 2.0ms 0.5% 0,0 _dispatch_worker_thread3 0x1753
在这里，我想展示应用程序崩溃的一部分（尽管可能没用），但它甚至无法启动我的应用程序。啊啊啊啊啊啊
等等 - 控制台日志！
