There may not be much you can do except for changing drivers such as rolling back to the default Windows drivers (or to some previous driver set). In the current absence of Windows 10 audio drivers for my laptop, I’m using the Windows 7 audio drivers in Windows 10 - Audacity recognises those drivers but not those for Windows 8.1.
Have you tried disconnecting Yeti and the web cam, then disabling Xonar in Device Manager then restarting Audacity? You could also enable Xonar but disable Realtek. It’s just a guess but it could be that if Audacity fails on one device it’s giving up on the others - it should not happen but this is a new version of Windows.
You could post your dxdiag report as well, but there is no guarantee it will help. Just click the search icon and type “dxdiag” (without the quotes).
