Cannot launch Karabiner Elements

I tried different iterations of these steps, but the one that ultimately ended up working was:

  1. Uninstall the app via command line (since GUI wasn't launching):

    sudo '/Library/Application Support/org.pqrs/Karabiner-Elements/uninstall_core.sh'
    
  2. Reinstall the app via the installer. Do not launch Karabiner Elements.

  3. Restart the computer.
  4. While it's restarting, hold down command+option+p+r to reset the PRam. Let go after the Apple logo appears the second time.
  5. Launch Karabiner Elements.
