The stacktrace suggests that the problem is caused by the Profiler . 堆栈跟踪表明问题是由探查器引起的。
Disabling the profiling and it should work. 禁用性能分析，它应该可以工作。 You can disable profiling by clicking end session in the profiler tab or by disconnecting the usb cable (when you have a real device). 您可以通过单击“探查器”选项卡中的结束会话或断开USB电缆（当您使用真实设备时）来禁用性能分析。
