my sims 4 studio is having a problem importing meshes, I don't know what the problem is and I'm trying to solve it, yesterday I spent 1h trying to import a mesh and at the end I got this message again!

I've already cleared the cache and I'm using the appropriate version of sims4studio for the game version I have installed

I'm redoing all the finished meshes that I had finished in order to understand if the problem is in them, hoping that's it because I don't know what else to do T_T

thank you for read and for your patience! ♥
