New World is a MMORPG game in which a ship sinks on an island and you explore the island, while joining different factions and participating in wars.
Like most of the others multiplayer games, New World has a lot of issues and one of them is the black screen issue that occurs after the characters are created by the players.
Usually the black screen lasts a few minutes before a server queue pop up shows up. All you have to do is wait your turn in the queue until you can play.
However, if the black screen problem continues for more than a few minutes, you may need to update your graphic card drivers.
Try restarting the game to see if that solves the problem. These steps should solve the problem as the black screen is often the result of the servers down with the flow of players trying to get into the game.
