Continuous Lockouts when Logging Into Apple Account from the Browser

Every couple of days if I try to access my Apple Account via a browser (Windows 11 Pro using Chrome), after entering my user name and password it shows that my account "has been locked for security reasons". I'm able to go through the unlock process, but I can't figure out WHY the account is being locked.

I've dropped any trusted devices, reset app specific passwords, etc., but it continues to happen. Is there any source of information where I can try to diagnose why this is happening? I don't think its someone trying to login to my account as I have 2 factor auth running (and only receive one when Im trying to login).

Its getting frustrating as well as concerning as I don't like the possibility of actually being locked out completely from my account.
