Audacity 2.4.x latest version will not open on Mac OS Catalina

This program will not launch on a brand new laptop.

Which exact version of Audacity do you have?
Have you installed Audacity to “Applications”?
Does Audacity appear in the Dock?
How are you trying to launch Audacity, and what happens?

Hi! i have the exact latest version of the application downloaded to the Applications folder and have not deleted the previous version from my computer. The application will not launch and I get an error message that says that must contact the developer. I have the latest Mac.

This message?

similar. Mine says “The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.”

Is that all it says?

It sounds like you have an old version of Audacity.
