Windows 10: My microsoft account says it doesnt exist whenever i log in

i got a security alert on my gmail so i changed the password and i am unable to log into my microsoft account as it says account doesnt exist, my microoft account that doesnt exist apparently is still connected to my microsoft store so i have proof that it does exist. all my emails related to microsoft other than microsoft rewards were deleted

Add Microsoft account to activation - doesnt exist in my settings

Confirmed. @maxima's screenshot is from 1511 (or earlier?) that part of Settings had an extensive makeover for 1607. These two screenshots are both from the same PC with different system images restored and logged in with a local account...

Microsoft account doesnt exist?

My family protected microsoft account will not show up when i try to log in (it continuosly comes up in the middle of my game or video pausing/minimizing it) and whenever i try to log in it always says "This microsoft account does not exist" so i am asking this on my alternate account now and i would really like help ASAP

 

Issue with Microsoft Store login saying account doesnt exist, how do I fix this?

I am trying to log into Microsoft Store using my account but when I do it says the account doesnt exist but when I click create one it says there is already an account using this email.

I was having trouble with my minecraft launcher so I went through many websites and many steps on how to fix the issue. One suggestion was reinstalling it, but when I did that I encountered another issue. To fix that issue I went through many websites and many steps again, one of which was logging out and logging back into Microsoft store. I did that. Now I can't log back in because of this issue.

That Microsoft account doesn't exist. Enter a different account or get a new one.

How the heck do I fix this? I saw a few other posts about this but they didnt help my situation at all. I have been sitting here for almost 3 hours browsing the internet and even asked others for help and it didn't work. This is really my last resort here.
