iphone – Settings –> Privacy –> Microphone shows “App Clips” as the only item, no apps listed, and the microphone does not work in any app

Taking up for example the answer of Microphone not working on third party apps only (iPhone 6):

Under Settings > Privacy > Microphone you’ll be able to allow/deny each app that require the microphone to use it.

I do not see any apps in the list. I only see one item called “App Clips”, and in that item, nothing is listed. How can I get back all of the apps that need the microphone?

The microphone is missing everywhere:

• filming with front or back camera,
• voice memos: you cannot even start the record,
• speech-to-text in Whatsapp, Telegram, Signal, Threema and just everywhere else,
• Siri,
• phone calls with or without headset.

This is just a list of examples that I tried, it is clear that it does not work anywhere else.

I have an iPhone 7 with iOS 15.6.
