Load model in Mold Design do not load tree

Hi,
in Zw3d2025 suddenly, in Mold Desgin, I have a problem when I try to load the model.
it should work like this (made with Zw2025).
After loading the model, it should create the layout (I don’t remember if the layout was generated before loading the model…) and import the part marked as Name_of_the_par_Product, like in the image below.

But now, the model loading doesn’t work. I don’t have neither layout nor Product part.
But those files are “not used files” with a path, so i cannot save them. see image.

Have any of you faced this problem?

hello,
with the help of support, we have identified the problem that is caused by using a custom assembly file.

leave it empty and everything works fine.
