10.0.40 Update

After installing the 10.0.40 update I can’t get any audio or even any audio activity from Cubase. I even tried 9.5 but also there. I see no audio activity at all in Cubase and no sound coming out of the system. I do get audio when I use another app and from webpages. I have a UR12 and reinstalled the yamaha driver and checked all the settings in Cubase but I cannot see any problem. The UR12 is the only active sound card. The only weird behaviour I see when I open a file is that the screen: loading vst mixer is flashing like crazy, which it never did before.

Cubase is fucked up but cannot find the cause. Please reply quick!
