TU24/1.16, Xbox One CU13
During gameplay minecraft sometimes crashes single player or split screen, all versions. This is a known bug called Extended game play crash.
Once game is reloaded and the owner of the played world is choosing saved game, during this screen just scroll up and down a second and the game crashes. This is new for 15 of May update.
Sometimes a saved game can be choosen fast and start to load and then crash. To fix this I restart the Xbox. Then it sometimes loads sometimes not and another restart of the Xbox is nessesary.
Added now 22 Maj that it is fixed if only one player is logged in. Other players must log out, then a normal game load can be performed.
Hope this was helpful.
