Error when clicking Object w/ Standalone Recolor Selected

When clicking Object with Standalone Recolor selected, there is a long loading period and then I get the following error message:

My game is up-to-date, I've repaired it in Origin, Sims 4 Studio is up-to-date, and my computer is up-to-date. I can't seem to find a solution anywhere. Thanks!
