Cannot use latest version

My mac won’t let me use the latest version - says “developer not recognized” - HELP - I utterly depend on this software - and am stymied without it. Is there a way I can revert to an earlier version, Please

I found my own answer:

To override your security settings and open the app anyway:

In the Finder, locate the app you want to open.

Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.

Press the Control key, then click the app icon, then choose Open from the shortcut menu.

Click Open.

The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
