"Microsoft Account doesn't exist" when it does

My account does exist, it's not locked, nothing is said that it's locked, I cannot recover the account because it's insistent that it doesn't exist, yet if I try and create another account with the same email, suddenly it does exist so I can't. I do not think I have any recovery emails or phone numbers linked to it, at least none of my own that I can remember.
I am on a different microsoft account than the one I need.
Unfortunately, I have cleared out my emails for that account from back to May, and I cannot see anything from Microsoft regarding the account. The account doesn't receive codes from Microsoft.
I have used this account for years, it has not been inactive at all. I've created a minecraft account with Microsoft this very year.
I have been waiting for almost two weeks, to hope the account is back, and I've been trying to sign in every day, I'm losing hope with the lack of options I have.
I can never name a time where I could've broken the rules, and that I could've been banned -- but it wouldn't make sense, considering even before I cleared out my emails I checked them, and there is nothing anywhere that says my account is locked, suspended, gone or banned.
