Suddenly my Yamaha Steinberg USB ASio Driver can not be loaded

Suddenly my Yamaha Steinberg USB ASio Driver can not be loaded. It says Device can not be opened and all I am left with is Generic Low Latency Asio Driver. I have deleted and reinstalled the Yamaha USB driver but it does not help. The files does not wok properly without Yamaha ASIO.
What to do? It is the same in Cubase 11. 10.5 and 10 abd eveb in Wavelab 11.

Hi,

I would try to reinstall the driver (download the latest one, please). If you are in Windows, install it as administrator, please.
