It’s entirely possible that the airfield was abandoned and removed from aeronautical charts, but is physically still in existence. I encountered this at Abbotsford, Wisconsin (ICAO Identifier KABB), which was actually Colby-Abbotsford before being abandoned sometime in the 80s or 90s. But the path of the main runway is still clear and the airport is listed in the MSFS departure/arrival fields on the world map.
If you do a search for the coordinates, any surrounding settlements, or perhaps the airport name itself if you have it, you might be able to find more information on it.
