Error Message in Sims 4 Studio

I'm trying to open a Mesh in Sims 4 Studio on my laptop and it's giving my this message:

What's weird is that I was able to create + open in S4S and put the object in-game on my computer but when it's on my laptop it's having issues (it can't open in S4S and is stopping my game from opening).
I actually had this issue with another mesh I created yesterday (it being able to work on my computer but not on my laptop), I tried that object again today on my laptop in S4S and in-game and it was able to work fine so it's an error that can be fixed, I'm probably just overlooking / forgetting something really simple - any advice is appreciated!
