It looks like you need to disable library validation for your app to load this library. Apple are getting stricter and stricter about what will and will not run on macOS.

You can do this in the 'Signing and Capabilities' tab of your project settings for your app build target (my app is called VinylStudio, in this example):

Then, hopefully, your library will load and the app will run.
