Development Programming & Scripting

Hello everyone,

I know I’ve already made a similar post, but I had new informations and I think it’s maybe better to create a new post for the visibility… : s

I’ve noticed that everytime I try to validate asset in folder in the City Sample project (matrix demo) I got an error and the editorcrash.

There is some animations for the accessories used by the methahuman, and the errors comes from here:

I really stuck here and have no clue on what I can do :cry:

Thanks a lot for help!!!
