How to fix Endless Microsoft Account Sign In Loop

For a long time now, I've been unable to access My Microsoft Account and Order History after my initial sign in to my Microsoft Account. After initial sign in, I click My Microsoft Account and it starts the Endless Sign In Loop (either states that it's unable to Sign Me In right now or kicks me back to Sign In page again).

I'm not able to:

1. Access My Microsoft Account--to change name, email, etc.
2. Access Order History--to view order history or cancel/manage subscriptions

I AM able to:

1. Sign into my Account (initially--first time only)
2. Reset my password via Reset Password link sent through email
3. Verify my account through email
4. Use Microsoft Authenticator App to sign in

I believe the fix is to the have engineering team unblock MFA or bad credentials for my account and remove the bad reputation.

Things I've done:

1. Tried accessing My Microsoft Account on multiple browsers, clearing the cache and cookies each time, also InPrivate window for Edge, Incognito for Chrome, and Firefox
2. Tried accessing My Microsoft Account on multiple devices and networks, home, work, mobile via cellular network and various WiFi networks
3. Contacted Microsoft Support and Xbox Support several times, having tickets made and closed as resolved.
