Loading a world that is created 1 year or more ago causes the game to crash

whever I load a world that is created 1 year or more ago causes the game to crash sending me back to the home screen. This has been happening since early February 2019 (before Peru) I been closing out the app and/or making a hard reset and neither any of them work. The crashs and the bugs are still there even if I closed the app and/or make a hard reset. This happends to all of my worlds that are created 1 year or older and happends all of the time. so this issue needs to be resolved soon!!
