Face ID not available? Stop working I tried everything?

If you still need help, reset Face ID, then set it up again. Go to Settings > Face ID &Passcode and tap Reset Face ID. Then tap Set up Face ID to set it up again.

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

Do you have a disabled Face ID alert on your device?

Please read the "What to do Next" section in this link, if nothing works as per the instruction given in this link --> If an alert says Face ID has been disabled on your iPhone or iPad Pro

My Face ID stopped working yesterday. I was able to reset it and get it working again, but today it stopped working again. I tried to reset it and restart the phone Face ID is still not available though.
