A developer uses AWS IAM Identity Center (AWS Single Sign-On) to interact with the AWS CLI and AWS SDKs on a local workstation. API calls to AWS services were working when the SSO access was first configured. However, the developer is now receiving Access Denied errors. The developer has not changed any configuration files or scripts that were previously working on the workstation.
What is the MOST likely cause of the developer's access issue?
The credentials from the IAM Identity Center federated role have expired. AWS Single Sign-On (SSO) typically provides temporary credentials, and once they expire, access to AWS services will be denied unless the credentials are refreshed. This is the most likely cause of the access issue, especially since the developer has not changed any configuration files or scripts.

C is the correct answer.
AWS SSO credentials are temporary and typically have an expiration time
