IFC import error

I have a problem importing from IFC. In AutoCAD Architecture 2020, I get an error on open an IFC.

Does anyone know what's wrong?

It appears your IFC contains objects ACA cannot translate: nothing to fix inside the program, perhaps another version of your IFC from another software might fix it.
