1.To run the bug you must write in the chat of a server or a realm, in most cases the game will freeze for an indefinite time, it can freeze for a short time or for a long time. In some cases when someone tries to restart Minecraft or close it when this bug occurs, the console will freeze and in most cases the console has to be shut down properly with the emergency shutdown option because it cannot be restarted, this bug already me It has happened more than once, the bug is very destructive.

2.-The bug that just happened to me occurs on the nintendo switch and mainly on my iPad since it does not let me log in to my account, I do not want to change my account and I have put minecons to my how many and I do not want to lose my purchases. To run the bug as soon as I log into Minecraft normally, first it happened on my iPad and now on Nintendo Switch, the last time I put my Minecraft account on my iPad and left it open, it wouldn't let me enter Minecraft, it freezes when they appeared the loading bars and now in nintendo switch it does not let me log in even so doing it from the page, I already tried it several times and closing and reopening minecraft and the same error continues to appear, I have a good connection and not even so let.
