The error code AADSTS5000225 indicates that the tenant has been blocked due to inactivity. This typically happens when a configured tenant is no longer in use and has not been accessed for a certain period. To resolve this issue, the tenant administrator can request reactivation within 20 days of the tenant entering an inactive state. If the tenant remains inactive for more than 20 days, it will be deleted and cannot be recovered.
If you are the administrator, you can reach out to Microsoft support to reactivate the tenant. If you do not plan to reactivate the tenant, it will be deleted after the 20-day period.
For further details on handling an inaccessible tenant, you may refer to the relevant Microsoft documentation.
