welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.
Could you enable GPG Suite beta updates and then check for updates. That will install GPG Suite 2019.1b1. Also consider updating macOS to the most recent version which is 10.14.5, since that contains a ton of important security fixes.
If the error then persists, please create a screenshot and send it our way.
