This one needs environment variables set before it will start: UNREAL_VERSION (Unreal Engine version to serve, e.g. 5.7 or 5.8 (default: auto-detect or 5.8)), UNREAL_PROJECT_PATH (Path to Unreal project for auto-detecting version from .uproject EngineAssociation field). The author declared them in the registry entry; get the values from the project itself.
