Spotlight Search not showing installed apps on my iPhone 14 Pro Max

Hello!

I'm experiencing an issue with Spotlight Search on my iPhone. When I search for installed apps (including system ones like “Calculator”), they don't show up in the search results. Also, in Siri & Search settings, the list of apps with indexing options is completely missing.

I’ve already tried:

— Restarting the device

— Resetting hidden suggestions

— Changing the system language

— Updating iOS

But nothing helped.

Please help
