Unfortunately, once your Microsoft certification has expired, you cannot renew it through reassessment. You will need to re-earn the certification by passing the required exam(s) again. It's important to keep track of your certification expiration dates and to take the renewal assessment six months before expiration to avoid this situation in the future.
For further assistance, you may want to check your Learn profile for any notifications or reach out to Microsoft support for guidance on the re-certification process.
