I cannot sign into xbox after I bought Minecraft, I tried another email which don't have a...

This is 100% a real problem and needs to be addressed. I found the same work around after not being able to sign in for days after purchasing something from the Minecraft store it signed me into someone's account I have no affiliation with, I have no clue
what the details for the email or password are and I cannot unlink it because I cannot sign into it. I have an account that I've been playing with since 2013 with a large amount of skin and resource pack purchases that I cannot get to. I have no clue who FiscalElk176123
is, it's clearly a generic name that was created I only have 4 email addresses and I've tried each one and each one is either not an account or an old Xbox account but none of it is FiscalElk176123. I have no emails that I do not remember just these four and
none of them are this account I don't get it.

when i accidentally tried to log in using another email it worked normally (that email does not have minecraft bought)

I've literally tried every email I can and I cannot at all sign in and I also don't remember the email whatsoever. I really don't want to make a entirely new ps4 account just to be able to play Minecraft with my friends.

Already tried all of that before didn't work as my account shows buy for minecraft java edition on the Microsoft store I am pretty sure that my account wasn't processed correctly after migrating I have even tried a fresh install of Windows and the xbox app. resetting the Microsoft store trying on a friend's pc that has migrated and was working but once I logged in on my username is shows demo only and only had 2 email address which I have tried both one wouldn't allow migration because I had another account on it but it made me make a new email during migration which is the one @outlook.com I don't have any other email addresses.

I see yes, I remember now. I just saw there is still one enforcement active and permanent. My brother used my email back in 2015 to create a profile on xbox. He got banned for cheating. So basically, I cannot use that email. Even though I bought minecraft with it on Mojang. Soo, I’ll have to once again buy it for another email…
