Hello Joe needs help please, welcome to Microsoft Community!
Based on your feedback, you are experiencing an issue where Windows 11 Professional has successfully added a work account using Entra ID, but is now unable to recognize the password to log in to the work account!
If you are the only global administrator for this account and are completely blocked, you can contact our support team. You can check the following article for a support number, depending on your country.

Or create a work order through another account：

When creating a ticket with the Microsoft Support team. Provide them with the tenant ID that is locked in the description. tell them that no administrator account has access anymore and that your partner no longer has access.
After creating a work order with the support team. you must work with our data protection team. For security reasons, you must first prove your identity to the tenant. Posting this team will help you access the tenant or unlock the account, depending on your scenario.
Additionally, in the future, it will be possible to create an Emergency Access Account (Break the Glass) in Azure AD. This account helps prevent accidental lockouts from the Azure Active Directory (Azure AD) organization if you are unable to log in for any reason.
