we are very sorry you are experiencing issues with the latest version of GPG Suite.
After investigating what is going on here, I can confirm that there's an issue if for one address both a OpenPGP key as well as an S/MIME certificate is available.
The good news is, that we have a fix for this issue and it's available in our latest nightly.
Could you please download and install our latest GPG Suite nightly build and see if the problem is fixed. That page also has sig and SHA256 to verify the download.
Disclaimer: This is a development version which has not been thoroughly tested yet - bugs or crashes are to be expected. Thanks for helping us test.
