thanks for getting in touch about this problem.
We have already removed all default keyboard shortcuts to avoid collisions in our code already. While this is fixed in the nightly build and will be included in the next stable release unfortunately users with existing installations have to disable the shortcuts manually in System Preferences > Keyboard > Shortcuts > Services. Look for any OpenPGP: entry and remove the shortcuts as desired.
Or you could switch to the beta channel as GPG Suite 2019.1b1 includes the fix. To do this open System Preferences > GPG Suite and tick the beta option, then check for updates.
