I cannot sign in to my microsoft account on minecraft for nintendo switch

This is not the first time I've signed into my Microsoft account for minecraft or Nintendo switch. I have tried multiple wifi connections, and the only error code it gives me is error code 500 and says xbox live cannot complete this request. I am able to log into my Microsoft account on the regular Microsoft website, just doesn't work for the website to connect it to my minecraft for nintendo switch

how do I link my microsoft account with minecraft on the nintendo switch. where do i enter the code?

I am experiencing the same exact problem, cannot link a microsoft account to a Nintendo switch for Minecraft. I get a black screen after entering my password on Xbox live.

Hello AbbySpencer,

Thank you for posting on the Xbox forums. We understand that Minecraft on the Nintendo Switch is signing your cousin into your Microsoft account instead of your cousin's account. We do not provide support for the Nintendo Switch on the Xbox forums.
We recommend reaching out to
