One I work with get this error all the time.
I have try updating he program to the neweste version (2020) both Autocad , Inventor , And Factory
It might be only be Autocad files that are Created by Factory but I am not sure
He can open the Drawning but when he have added at one or just a few dimension it will get this Error and close the program
