macOS Catalina: "App is damaged and can't be opened. You should move it to the trash."

Solution 1:

Here's the solution. Open Terminal and run:

sudo xattr -rd com.apple.quarantine /Applications/Coherence\ Pro.app

If the path to the program is different, then obviously change it so that it's pointing to your app. For me, I've had several apps not working after the update to macOS Catalina. This takes care of that problem though.
