Unfortunately Contacts And Dialer Has Stopped, Miui 9.6 8.4.12

Mar 22, 2016
Good evening dear friends,

Installed today on my brand new Mi Note 2 128GB Xiaomi.eu Oreo ROM:
MIUI 9.6 8.4.12

Everything smooth as silk, only one important thing, I cannot use dialer and contacts, I receive the following message :
Unfortunately contacts and dialer has stopped
I realized that while the Mi Account is active, the Phone and Dealer apps can't be launched since I get the thread title error.
So from what I understood reading here and there, this issue indicates a fake rom. But this one brand new installed is from this forum.

Some advices?
