Well.. the problem was embarrasingly simpler than I thought. For some reason the Cubase had resetted the ASIO driver from Asio Scope to Asio multimedia driver using the windows drivers. So all I had to do was to go to Asio settings and switch it back to Asio Scope.
This was not a real problem as you can see but I managed to waste 3 hours of my precious composing time and lose my intuition for today
