Disconnected Players Can't Select Singleplayer Mode With Crossplay Enabled

Players who were disconnected from the network or who aren't connected to any internet settings will be presented with a momentary black screen when selecting Singleplayer Mode, before being returned to an inaccessible version of the Main Menu. 

Workaround: Disable Crossplay in the game settings or connect to the network before selecting Singleplayer.
