Garmin express on windows does not recognize Fenix 6X since last firmware update

Since last firmware update (16.70), garmin express does not recognize my fenix 6X.

Before that firmware version all was ok with the connection.

The computer does recognize the watch, and i can access its folders.

But garmix express does not.

I've upgraded to the last version on garmin express.

My fenix 6x is new, because it was sent last month by garmin, (the old one had battery drain issues and they sent me a new one)

Does any one know a way of connecting fenix 6x to garmin express?
