I've had this issue with minecraft where every time I try to play it, the game closes. I play on nintendo switch and for the past week or so it closes after loading to get to the main menu. I rarely get to the main menu before it closes, some times I get to load a world and it closes while its loading. I've gotten to play it about 4-5 times without out it closing. On my switch, I'm the only one that plays and this only happens on my account. I've been able to load the game successfully on all the other account besides mine. P.s. It closes on the white screen with the mojang symbol. The Affects version/s section might be wrong my version of minecraft for the switch is 1.12.0 but its all up to date
