### Describe the bug

I created an app using my account in N.Virginia region. When i try to create another app using the same account and region, i am getting the error "Houston, there's a problem Failed to create app. You have reached the maximum number of apps in this account. aws amplify error". I have another account same as this, this problem never existed. I can create many apps in that account.
When i checked they told me to check the service quotas, but i have only one app in that account.
Even if i change regions, same issue persists.

### Expected behavior

Creation of new app along with the app which is present in the amplify console for the same account.

### Reproduction steps

1. Create a new account for integration environment

3. create a new app(Host a new app). Complete creation of this app
4. Create another app(Host).
5. After pressing save and deploy, There will be this error "Houston, there's a problem Failed to create app. You have reached the maximum number of apps in this account. aws amplify error"

Start with the linked FAQ and AWS service quotas, then reproduce the issue in the Amplify console using the listed steps and us-east-1. Compare the account's app count and behavior across regions. Done means identifying whether the account limit is incorrect and documenting a verified resolution or an actionable escalation.
