Based on your description, I understand that you have a query "Developer E5 Subscription expired".
In general, our primary focus on this community channel is addressing concerns related to Microsoft 365 Exchange online mailbox or Outlook services. However, Microsoft offers specific community channel resources where our esteemed professionals and community members can provide valuable information pertaining to various support scopes and resources. Would you kindly consider connecting and sharing your concerns on our dedicated Microsoft Developer program community channel at Office developer community to obtain further possible information from our community members?
Here is one thread URL for your reference: Microsoft 365 developer program - dashboard E5 subscription add phone for security error. - Microsoft Q&A
Also, you may need to Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn and get Microsoft Data Protection team engaged for this issue via phone support option so that they can help you from the backend. They might be needed to change the verification method to you for security checks or verification.
