“Content and Privacy restrictions” deletes my App Store app

I have an iPhone 15, iOS 17.5.1. When I turn on “content and privacy restrictions” so I can block “in app purchases” it deletes my entire App Store app so I can’t download any apps at all! But I can’t turn off in app purchases without turning on “content and privacy restrictions”! How can I block in app purchases while keeping my App Store available to download new apps?

(and don’t tell me that my App Store is “hidden in my App Library”! It’s. Not. There. As soon as content and privacy restrictions gets turned on, the entire app disappears. Not in the library. Not in systems. Not in search. Nowhere on my phone. And it doesn’t reappear until I turn off content and privacy restrictions.)
