Unable to log into personal MS account, had to reinstall Win11, MS Authenticator not configured anymore

I had to reinstall MS Win11 to attempt to correct errors. somehow, personal account appears to somehow be tied to a work account that no longer exists, and I no longer have access to that account.

I am unable to configure MS Authenticator as it believes it should already be configured. I have a lot of data in OneDrive that I do not want to lose.My MS 365 Account is tied to my outlook.com account.

I have been getting error indicating I cannot use a personal account to login. I have a lot to lose.
