Problem with uninstall app store

If you mean that your App Store app is missing:

The App Store app is not one of the apps that can be deleted but it can be removed from the Home Screen. Go to the App Library (swipe left past your last Home Screen). From there you can touch and hold an app and slide it to the Home Screen.

Also note the Search window at the top of the App Library.

Another reason for it not being visible is due to a restriction on purchasing. Go to Settings and tap Screen Time, tap Content & Privacy Restrictions, tap iTunes & App Store Purchases, choose a setting and set to Allow. Also see the following Apple Support article for more information: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support

or if you mean that you are getting a message that your account is disabled in the App Store:

If your account has been disabled in the App Store and iTunes, it isn’t something that you can fix yourself. You will need to contact Apple Support. The following Apple article includes a link that you can use to contact Apple Support: If a message says 'Your account has been disabled in the App Store and iTunes' - Apple Support
