[SOLVED] Opening Commands causes Rhino to crash immediately

Hello,

After rebinding several keyboard shortcut commands yesterday, Rhino crashed. Now, whenever I click Commands > Customize, the program crashes. The issue persists even after uninstalling and reinstalling Rhino.

I typed Commands List into the console and it output the following information: "Unable to load plug-in “/Applications/Rhino 7.app/Contents/PlugIns/ Import_DGN.rhp.” (screenshot below)

Does anyone know a potential fix?

UPDATE:
I was able to open Commands through settings, but the screen remains blank:

Update— [SOLVED]:

I followed the directions to reset my preferences, as described at this link: https://wiki.mcneel.com/rhino/mac/resetprefs

This fixed the issue.
