error opening sound device [SOLVED]

As you can see, there was no screenshot in your first post.

As you can see in your now posted screenshot, you don’t have any enabled recording devices, hence Audacity cannot record.

So, quit Audacity, then open Windows Sound, Recording tab. Follow the steps in that Windows Sound link, starting with "Recording Settings: Right-click anywhere inside the Recording tab and choose “Show disabled devices” then right-click again and check “Show Disconnected Devices”.

If you need more help, PLEASE, give us the make and model number of the recording device you are trying to use and describe how the guitar and mic are connected to that device. If it is an external interface device, you may need to visit the web site of that device then download and install Windows 10 drivers for it.
