AWA APP Studio Message "401 Authorization Required" when creating or editing my own app

It sounds like you're experiencing an authorization issue with AWS App Studio despite having both Admin and Builder roles. This could be related to service role permissions or IAM Identity Center configuration.

Since you can sign in and create apps but encounter a "401 Authorization Required" error when trying to edit them, here are some potential solutions:

1. Check if the service roles for App Studio have been modified. Changing permissions for a service role might break App Studio functionality. Service roles should only be edited when App Studio provides specific guidance to do so.

2. Verify your IAM Identity Center group assignments. As an Admin, you should have access to the Admin Hub with full permissions to manage applications. Make sure your user account is properly assigned to groups with the Admin role.

3. If you're using the AI prompt feature, try rephrasing your prompt. Sometimes the AI builder assistant may encounter errors that manifest as authorization issues.

4. If the problem persists, you might need to check with your AWS account administrator to ensure that your IAM Identity Center configuration is correct and that you have the appropriate permissions assigned.

Remember that in App Studio, roles are assigned to IAM Identity Center groups, not directly to individual users. Each member of an added IAM Identity Center group will be assigned the role that is assigned to the group.
