OS X EC can't open Audacity 2.1.2

I know this question has been covered before in previous versions, but no matter what I do, I do not get a dialogue box that gives me the option to open this app. I have tried opening the app through Finder and using the Control button to open the app (as suggested in previous postings), but, regardless, the dialogue box simply states, “This app can’t be opened” and then “ok.” Would really appreciate any insight. Or even validation at this point. Thank you!

The current version of Audacity is 2.3.0, which is available via the Audacity website. Installation instructions are on the same page: https://www.audacityteam.org/download/mac/
