New AWS account cannot access Textract or App Runner – redirected to “Complete your account setup” page

I recently created a new AWS account and am experiencing an issue where certain services (such as Amazon Textract and AWS App Runner) cannot be accessed.

When I attempt to open these services in the console, I am redirected to a page that says:

Complete your account setup Thanks for signing up for Amazon Web Services. If we have directed you to this page, then you have either not finished registering, or your account is currently on free plan.

However, my AWS account registration appears to be complete, I received the email confirming that my AWS registration was successful, I have AdminAccess permissions, and I also attempted access using the root user.

Additional details:

• Account created within the last few days
• Billing information was provided during signup
• Support ticket opened >72 hours ago, but no response yet
• Issue occurs when attempting to access services like Textract and App Runner

Has someone dealt with this before? If so, how do I get these services to work? This is time-sensitive because my clients expect me to have my app deployed on AWS ASAP, and the only delay is this issue.
