Hi @Econa77, thank you for the awesome app!

Since I upgraded to macOS Mojave, Clipy no longer opens. It spews an assertion error from realm-core:

@hooveraj commented on GitHub (Nov 26, 2018):

Since upgrading to Mojave, Clipy opens but periodically freezes (spinning beach ball when I hover over the icon in the menubar, etc). In Activity manager, it shows as not responding. I wonder if I'm seeing the same error. What logs can I provide that would be helpful, and how do I get them?
