Cubase 12 suddenly not recognizing Scarlett and Steinberg USB drivers

Help, I am in the middle of a project, and Cubase 12 Pro will not recognize my USB drivers ( Scarlett 4i4, and Steinberg Yamaha mixer USB.) I have tried reloading both these drivers, but Cubase 12 doesn’t acknowledge/load them.

Hi,

Do you see them in the Studio > Studio Setup > Audio System > ASIO Driver?

Could you try to reinstall the drivers? If you are on Windows, make sure, you install them as administrator, please.
