Hi,

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. Since your question is related to Office 365, which is not in our support scope.

However, I found a document that mentioned Microsoft 365 Developer Program members who created an instant sandbox on or after September 30, 2022, may be unable to sign into their subscription with their admin accounts because they have expired. Members with existing instant sandboxes created before September 30, 2022, are not affected.
For more details please refer to: Microsoft 365 Developer Program instant sandbox update - Microsoft 365 Developer Blog
