Question

我正在使用Windows 10。

在将VS 2017更新为15.8.1之后，我开始出现以下错误：

The "Copy" task failed unexpectedly.
System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.
   at Microsoft.Win32.Win32Native.CopyFile(String src, String dst, Boolean failIfExists)

我试图将项目移动到另一个物理驱动器，但这没有帮助。

项目可能会有所不同，并且错误不会在每个构建中都重复。可能导致此错误的原因是什么？
