The linked PR has a fix and a unit test for the fix using both the config system and the constructor.

However running the configuration tutorial on Windows will lead to issues with XGBoost as the XGBoost binary that the developers put on Maven central doesn’t have a Windows dll in it, only macOS and Linux. It’s possible to compile XGBoost 1.0.0 (which Tribuo 4.0 uses) for Windows (I’ve done this for internal use and contributed fixes for it upstream) and then adding that dll to the XGBoost jar next to the so and dylib will make it work.
