Ring but I cannot answer, nothing on the screen

Since 3 weeks, when I get a call there is nothing on the screen.
The phone ring but I cannot answer. When the person hang up, I’ve a missed call and I can call back but I can’t answer before.
I have no problem with rhe call from internet (messenger, skype).

I did the last update and reboot several times, but still not working.

Some ideas ?
