Screen goes black when hitting call

[Gera1]

Once I hit call the phone goes black, and the call does not connect, the phone app stays black but the rest of the phone is completely functional. The call reconnects about a min after I press call.

Check if the same occurs in safe mode:

If you do not face the problem in safe mode, please uninstall chrome update from app menu in settings. Let us know if it works.
