“复制”任务意外失败

Question

I'm using windows 10.

After updated VS 2017 to 15.8.1 i started getting error below:

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)

I've tryed to move project to another physical drive, but it wasn't helpful.

The projects may vary and error is not repeating every build. What may cause this error?
