Windows - Linux Build Error

Gentlemen, there is a problem in the project building.
Windows 10. Engine - 4.21 Source version. C ++ project. Visual Studio 2017.
I’m need to make a build on the Linux platform, but an error occurs. Moreover, the project on Blueprint is successfully being built. I read all sorts of guides, installed the Linux Tool Chain of the required version, but I still encounter this error in the photo.
[ENG] Error text - “ERROR: System.ComponentModel.Win32Exception (0x80004005): The specified executable file is not a valid application for this operating system.”.
There are possible solutions to the problem?
P.S - Sorry for my English :slight_smile:
