Changing settings / opening Safe Mode crashes

Whenever I try changing any part of the Settings / Preferences, the Accordance app crashes and triggers this message:

This message also shows up when I try entering Safe Mode. I would try to use any of the Safe Mode options, but it would crash and trigger the same message.

Please help, as I would like to change some preferences and settings on my Accordance instance.

I'm on MacOS Golden Gate 27.0.
