Variaudio not working

Hello,
Since I installed Cubase 14 Pro (upgraded from v13) i cannot use Variaudio. I sorted out that if I switch the Asio driver from the yamaha steinberg usb asio driver to the steinberg internal asio driver it works fine.
Running windows 11 and the yamaha steinberg usb asio driver is version 2.17
Audio device is Steinberg UR44C
Who knows how to fix this?
Thanks
Bouncing audio part does not solve the issue
