This was a prior version of Boeing's bid for the Human Lander System under NASA's Artemis program, in partnership with Intuitive Machines and drawing from Starliner heritage. It was a scaled-back version of a previous Boeing concept, with roughly the same ascent stage design but a drastically simplified descent stage (eliminating the expendable habitat and airlock module). However, it was short-lived, featuring in only a handful of PR materials for a few weeks before being replaced with the current (as of April 2020) proposal in November 2019.
