This error means that your project file (the .cbproj) contains more than one <ProjectExtensions> section. Open the project file in a text editor and remove the duplicate.

This is often caused by an upgrade from an older IDE version. The IDE ignores it, but the command-line compiler and TwineCompile require the project file to be correct.
