This is the setting of my finger print it's empty i can't add the finger print

I checked it and do all the updates

What option

I did the latest update and it keeps happening but the last few days my phone dropped alot on the floor may that affect the finger print?

It's clean like normal but there is a message when I try to inter my finger print says that the finger print not working now and it's kept happening since 4 days I bought my phone 2 years ago and it is the first time this happens
