Mac App UI issue when trying to change the accent color in profile

I just discovered the MacOS App (not sure how I missed it for so long!) but I’m having some trouble with it.

When i try to pick the accent color in the profile, the UI color picker starts blinking and the app freezes up until I can hit ESC enough times to stop it.

I’m on MacOS 10.15.7.

Anyone else having a problem like this? I can’t find anything similar in any of my searches.
