Why does the fingerprint sensor suddenly stop working?

I have a Huawei P10 and yesterday and the days before I unlocked it normally via fingerprint, but yesterday evening it stopped suddenly and I reset it this morning and then he was there for a moment and then I have my finger reconfigured and then the option was immediately gone afterwards (picture follows)

How can I fix the error? (Can only access the fingerprint menu through the search

It's Android 8.0 and EMUI 8.0.0 on it, so the latest here in Germany for the P10

How about washing your hands and trying again

Is probably due to your ugly font.

You're funny, I've already tried.

Schicks to the support where do we know this with 2 screenshots that say nothing

There are some people who know something like that

Did it synonymous with the standard font tried, is not synonymous
