A cloud-based identity and access management service for securing user authentication and resource access
Thanks for reaching out to Microsoft Q&A. I'm sorry you are going through this issue and hope you be able resolve this expeditiously.
That said, AADSTS5000225 usually means the portal is landing you in an Entra tenant that has been blocked due to inactivity, not that your personal Microsoft account password is wrong. You can request reactivation within 20 days of the tenant entering the inactive state; after 20 days, the tenant is deleted and can't be recovered. If this was your only tenant, and it is already past that recovery window, you'll need to work from another active directory or create a new tenant instead. See: https://learn.microsoft.com/entra/fundamentals/inaccessible-tenant#overview
If you can still access another active directory with the same account, switch directories in the Azure portal under Settings > Directories + subscriptions, then go to Microsoft Entra ID > Overview > Manage tenants > Create to create a new tenant. Another thing to note also, is that only paid customers can create an additional Workforce tenant from the admin center; customers on a free tenant or trial subscription can't create additional Workforce tenants there and may need to sign up for a free Azure account to get a new tenant.
