Microsoft locked me out of my account and won't let me back in

i was locked out of my account that I've been using for about 10 years, around 8-10 months ago out of nowhere with a popup telling me

" We have detected unusual activity on your Microsoft account my account, or believe your credentials are at risk.

For your security and to ensure only you have access to your account, we will ask you to verify your identity and change your password."

ever since i've been filling out the forms twice a day to no avail following guilds and whatnot. i really hope i wont have to to resort to making a new account and having to lose my minecraft account with it(which is linked to my account and as of writing this i have no clue if i can change the linked account) as well as starting fresh.

should mention that i've been doing all of this on my computer that is actively (somehow still) able to login using my account
