macOS: Application cannot be opened because the developer cannot be verified

[appdev44]

When running sudo-prompt on OS X 10.15.7 from nw.js application - I get a pop-up "Application cannot be opened because the developer cannot be verified - macOS cannot verify that this app is free from malware".
This works as expected on OS X 10.14.x and 10.15.2 - only started getting this issue from 10.15.6.

from the console - 2 sets of logs:
Set 1:

In system preferences - Security and Privacy - it shows up under "allow apps downloaded from" - and has an "open Anyway" button - but this does not help, since it will be a difference "process" each time you run it.
Also get the issue on macOS Big Sur
thanks
