It looks as if a library part in a referenced IFC file has errors in its script. To remedy the situation there are three things you could do:
1) turn off "Interrupt with error messages" in Model Rebuild option portion of Work environment and turn off "Enable ArchiCAD sounds"in More Options of Work environment. This will continue processing views etc without interrupting to work flow but will not fix the error
2) find "mechanical fastener" objects and delete / move on to layer that is not turned on
3) fix GDL scripts of invalid parts, This could take many hours / days of work for probably little / no visible change in the model.
I would question why you need mechanical fasteners in your project this I would have thought to be unnecessary detail that will just slow down the project. when importing the IFC model you can choose what classes of information to import, turning off unnecessary information will speed up import and working generally.
