Error occurring when I try to use a specific package

Hi all, I'm wanting to create a selective clone of a cc package from a long inactive creator (object will occasionally disappear when placed in game, and wanting to make some recolors), I'm getting the following error when I try to open it in s4s. On the most current version of s4s and sims 4, game works, package works in game, just can't open it in s4s. Is there any way around this error, or am I SOL with this package?

The Sims 4 Studio - Version 3.1.4.2
