I assume you're referring to Microsoft Certified: Azure Solutions Architect Expert,
To become a Microsoft Certified: Azure Solutions Architect Expert, you must earn the Microsoft Certified: Azure Administrator Associate certification (i.e. pass AZ-104 exam). This needs to happen before your AZ-305 certification expires.
If you passed AZ-305 in September 2023 and haven't renewed it, it's already expired and you'd need to take this exam again.
