Nobody turned it off, if you have issue follow steps here If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support

No details?

How to use Face ID:

Face ID not working?

Try the following:

▷ Update your iPhone. 📲

If that didn’t help, then try a Hard Reset:

1. Press volume up (quickly)
2. Press volume down (quickly)
3. Press and hold the power button until the Apple logo ( ) appears

If that didn’t work, it could be a hardware issue. ⚠️
