The update couldn’t have caused your Face ID to stop working. But it rather sounds like a pure coincidence. Most times when Face ID isn’t working, there is something wrong with the TrueDepth camera, which is the hardware behind it. Please review the following Support Articles to do basic troubleshooting.


If Face ID isn't working on your iPhone or iPad Pro - Apple Support

If an alert says Face ID has an issue on your iPhone or iPad Pro - Apple Support


If the above doesn’t help, this is likely a hardware issue that needs to be taken a look at your nearest Apple Store’s Genius Bar or Apple Authorized Service Provider.
