Minecraft nintendo switch edition is completely unstable

Every time you start the game or reload the game and sign back in you cant chose skins except for the mario ones and to chose other skins yoh have to go on a world and wait for about 1 minute before it auto quits and take you to the menu. From now its normal but this is really fustrarting. Also after about 3 times leaving a world you crash. And it crashes alot during gameplay. These crashes happen oftenly and are super annoying because you have to repeat what i said in the start.
