Well now, that's interesting. I include LibreOffice v5 with my standard install of Mojave. I ran a fresh install earlier this week just to test the upgrade, which worked. Only then did I try opening the applications. And LibreOffice v5 opened without a fuss. I read this article and tried downloading v6. Sure enough, I hit this exact issue. That's seriously inconsistent Apple. Thanks for the unnecessary grief.

Surely this cannot be a problem caused by the LibreOffice developers and must be Apples fault. After all, it only happens in one version of the application and not the other!
