Audacity does not officially support Windows 10 yet.
If you have not already done so you should go to the web site of the computer manufacturer or motherboard manufacturer and see if you can find the latest audio drivers for Windows 10 meant for your specific computer model. If new drivers are there, these might be better than the audio drivers that Windows 10 found itself.
The situation is fluid, so also keep using Windows Update and use Windows Device Manager from time to time and try the right-click option over the audio device to update the drivers.
If that does not help please see https://forum.audacityteam.org/t/internalportaudio-error-since-windows-10-update/39286/1 for other things you can try.
