I,m having a problem similar to yours.
Sometimes (maybe 1 out of 5 attempts) when I try to start Cubase I get a message “Yamaha Audio driver was removed” and Cubase wants me to choose between three drivers: ASIO4All, Generic and Ymaha/Steinberg.
However, the PC has freezed, I cannot choose, move tje mouse cursor, start activity or anything. The only thing I can do is to shyut down the power and restart the PC.
I have a Lenovo stationary PC with SSD harddrive, Win 10 64-bit.
