Error 9

Hi. Contact to know what to do in case of error 9 on Nintendo Switch. I open the program and I get this error along with a mojang help tag which will not let me in from the Nintendo Switch. Spend a couple of seconds and the program automatically closes. It also says that you have had a login failure, although you have logged in multiple times. I've been answering error for about a month. The version is not correct, it is the Minecraft for the switch. Thank you
