Nice long report
Actually, as I see, the report says:
Fill not found, not File not found.
So the 3D Script of your object is missing a Fill Type.
Maybe you delete a Fill Type from your project in Options\Fill Types or in Attribute Manager, but your object still refers to it and tries to use it.
You should check all parameters of the object to see if any one of them is trying to use a Fill and it says 'missing' as the selected Fill type.
Also check the same among the setting in the Floor Plan and Section panel of the Dialog.
By the way, the reason the error message comes so many times and you have to click Continue is because there are many instance of this problematic object.
