I have a big problem that Microsoft says "account doesnt exist" but i literally own minecraft on it and im worried that i lost all of my data on minecraft

Well, i will try my best to explain everything and every detail possible, it starts me trying to login to Minecraft and the usual putting my email on it, but then it says "account doesn't exist" I just thought it was an error so I went to search it how to fix it, I watched some Youtube videos, reddit posts and even Microsoft posts to fix it, but after I realized that it was really late like 1 A.M but it was new years so no big problem I went to sleep.

But now today, I remembered about my Microsoft account and I began to think what if I just put in the search bar "why Microsoft says that my account doesn't exist" and then I started to realize that it was "impossible" to recover it and I was sad, BUT then I realized too, that if I bought Minecraft in that account, does the ownership of the disappear, or if I create a account with the same email address does Minecraft recognize it, ect. and ect.

So the last thing that comes to my mind, is make a post on Microsoft to resolve the problem. But is probably gonna take some days to figure it out.

Thanks for the people that try to help me but "what if you try to recover your account?", "send a letter to the Mods and later they send you one", without my account because its completely deleted from the platform, they cant send me emails to recover it, because the only answer that i'm gonna get is "We can't help because, your Microsoft doesn't exit, Sorry".

Plus I forgot to add something, my account is personal, not for education/for a student, which some tutorials on Youtube, required me to have one to fix the issue.

UPDATE MUST READ: Well my account is completely deleted, which is sad and plus my account is a child account which wasnt in a family group so it got deleted, so now i gotta buy Minecraft again in my new account"
