Hello,
Apple has several documents helping you with Face ID.
This Support article is specific to seeing a 'disabled' Face ID alert, and explains what to do when you see that notice. --> If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support
If you don't see a 'disabled' message but do have general issues with Face ID not working properly, explore the list of things to try in this document: If Face ID isn't working on your iPhone or iPad Pro - Apple Support
If the first 8 don't solve the issue then use #9, contact Apple.
If you see a camera error because of an unknown part, that is explained in this article About genuine iPhone cameras - Apple Support
