Changed microsoft account email lost access to minecraft account

To start, I initially reached out to Mojang support for assistance; however, they advised me to contact Microsoft support instead. The challenge I'm facing is that whenever I attempt to contact support, I'm consistently redirected to this page beacuse as they said to me in many email: "Thank you for replying back. Unfortunately, we cannot provide information regarding an account. But if what you're asking is if you can see what email is linked to an account without signing in is something that can't be seen." I basically asked them if they can change the email address associated with my account or, at the very least, provide me with the information about the current email address

My recent encounter with an issue occurred when I attempted to launch Minecraft after a 3-month hiatus. I noticed that my account had been logged out, and when I tried to log back in, I was directed to the new launcher, which stated that I didn't possess a valid account. I'm certain of both my email and password, and I can access all my email accounts, but it appears that my ability to log into my Minecraft account has disappeared.

I purchased Minecraft from the official site using a MICROSOFT ACCOUNT to log in. However, when I tried to log in, it said that my account needed a password reset. So, I went ahead and reset the password. After that, it instructed me to enter a "nickname" so I entered my Minecraft account nickname. Surprisingly, it informed me that the nickname was already taken. In an attempt to resolve this, I quickly created a new nickname, thinking it might be an error. However, setting a new nickname did not lead me to my Minecraft account. When I tried to download Minecraft again, it indicated that "I do not own this game" or something similar.

I kindly request that you refrain from suggesting that I change my password, as I am confident in my knowledge of all my passwords and can successfully log in to my Microsoft account. The issue seems to lie in the disconnection between my Minecraft account and my Microsoft account.

If it's relevant, I exclusively utilize the Java edition of Minecraft and have never ventured into the Windows 10 or Xbox versions.

I also have a transaction ID and still have access to the email that my Microsoft account used to purchase Minecraft
