There is a person logging in as a minecraft account

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Andres, If you think there is a possibility that someone is logging into your account, please follow the steps in the link below.

Secure your account after you've been hacked

We understand that the two accounts can not be linked. My son has set up the PC with his personal Microsoft account. But I have bought the game through Mojaang via my personal Microsoft account. It is however asking us to log into the store with a business or school account. I was hoping to link Minecraft with my business account instead of my personal account and make it work that way around.

I did not directly subscribe to Microsoft 365, my family has a familiar plan if I recall correctly it was called, or a company plan, which let's us add several accounts, and manage it, my account was not the manager, so Microsoft 365 is not a problem.
I just logged into the account and checked to make sure, and no, none of the things are in the services listed. Although I cannot confirm this, I think when I first checked after recovery, before Microsoft 365 was moved to a different account by the manager, it was still not there anymore.
Yes, I have tried to log-in using the account into Mojang's main page, as well as Minecraft Launcher, and even Mojang.com. In all of them it said that there was no minecraft account linked to that account, and trying to log in with the Minecraft account as before migration, would still say the account existed and was migrated to a Microsoft account.

I want to make sure it is clear, Microsoft 365 is not a problem thanks to it not being a personal subscription, but a groupal one. At the moment the main problems are that my minecraft account seems to be linked to a wrong Microsoft account, or has somehow been unlinked, and I am scared of the possibility that personal information like credit card information could be in that account just like my Minecraft account.

I am now editing this reply just a minute after sending it, as I checked to be sure of what it said, when I log into Mojang's main site with the Microsoft account, the Gamertag is the same as the "old" microsoft account was "***Remove PII***", and it says I do NOT own Minecraft: Java Edition.

EDIT: Removed personally identifiable information (PII) from post.

I don’t think it has to do with that. When I log into the Minecraft website it says that I have Minecraft purchased, it won’t let me log in with this account into the Minecraft launcher. Whenever I click log in with Microsoft or I click on my account to log in, it says that there was an issue while logging in.

I logged off the minecraft account, restarted computer and opened minecraft, and logged on server, still doesn't work
