recent CopyQ versions not working on MacOS Mojave

I'm currently running 3.1.2 on two Mojave machines and wanted to try the pin feature and went to upgrade to 3.7.2. It can not run properly.

1. `brew cask install copyq`
2. `copyq --version; copyq` to confirm version and that it runs from terminal
3. start CopyQ.app from launcher and receive an error '"CopyQ.app" can't be opened because it is from an unidentified developer.'
4. MacOS preferences/ security / click lock to make changes / and permit this program. Click to open.
5. Affirm another popup: '“CopyQ.app” is from an unidentified developer. Are you sure you want to open it?'
6. After clicking `open` nothing happens. CopyQ is not running.
