I tried this but am still not able to load Rekord Buddy 2
I moved your post to a new thread because it’s not the same issue has the one you were replying to.
A little but more context is needed here, I’ve never seen this error before.
What version of macOS are you using? Do you get this dialog when you double click on the app?
It looks like this is a Catalina thing. You should be able to get around it by right-clicking on the app and select Open.
I’m looking into a proper fix.
