An error with sims 4 studio

Hello everyone,

I am experiencing an error with sims 4 studio, with just some items but not all,

For example the GP01 debug tree "treeGP01_EverGreen_01" 


I get this error directly after requesting to save the file :


The Sims 4 Studio - Version 3.2.1.7

System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.)

I have already repaired my game, uninstalled and reinstalled Sims 4 studio, the access paths are also correctly indicated, I deleted all the files in my documents folder but nothing happened.

Thank you for your feedback,
