Omnigraffle 5 Crashes on Launch After OS Upgrade to Mojave

I recently upgraded my OS to Mojave, and now when I try to launch OmniGraffle Professional 5.app it crashes when trying to open. How can I fix this?

Two options, I think:

  • You could downgrade the OS to a version that can run OG5,
  • or upgrade OG to a version that can run on Mojave.
