Have you tried, as the error message suggests, re-installing the Audacity app.

The latest version is 2.2.1 - and you can get it from here:

Update: I just checked my installation of 2.2.1 on my W10 laptop and that dll certainly comes as part of the download.

I usually google for the driver, download and install it, to fix such problems.
Win 10 is supposed to do that automatically but if not then just DIY.

It is a little odd when it fails…

Virus software?
