New user - need help with ERROR -9999

Windows 10
Audacity 2.4.2
Turntable: Audio-Technica AT-LP120XBT-USB

I viewed the Audacity video on setting up Audacity and set it up as suggested. When I click the “record” button or the “record level” bar I get:
Error opening recording device
Error code -9999 Unanticipated host error

Any help solving this issue is appreciated.

Which video?
