Face ID is not working on App Store

Face ID in App store not working on my iPhone 12 Pro Max after updating to iOS17.2.1. What Kind of measure i want to do to resolve this issue.

Hi bro, it could be temporary bug. once disable face id toggle for appstore under settings - face id and passcode - appstore section. Then restart iPhone once. again come back to same setting and toggle it ON.

Then check if face id works on appstore bro.
