无法启动执行程序 - uipath 中的 Trycatch 错误

问：

在 UiPath Windows 进程中，我尝试在 try catch 块中抛出错误。在尝试中，添加了两个分配活动，机器人能够成功传递这些活动，然后我分配了一个用于测试的抛出活动。机器人引发错误，但无法移动到异常部分，并且失败并显示错误“无法启动执行程序”。

**错误信息：**

system.Exception: test   at System.Activities.Statements.Throw.Execute(CodeActivityContext context)
   at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager)
   at System.Activities.ActivityInstance.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)
   at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)
--- End of stack trace from previous location ---
   at UiPath.Executor.BaseRunner.EndExecute(IAsyncResult result)
   at UiPath.Executor.InProcessRunner.EndExecute(IAsyncResult result)
   at UiPath.Core.Activities.ExecutorInvokeActivity.EndExecute(AsyncCodeActivityContext context, IAsyncResult result)
   at System.Activities.AsyncCodeActivity.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result)
   at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

我尝试在 try 块中仅添加抛出活动并在 catch 块中打印异常消息。但它在 try 块中抛出错误，但它未能在 catch 块中打印异常消息，并出现 cannot start the executor 错误。

另外，我尝试更新所有软件包。但错误仍然保持不变。
