I think I have a corrupt part file. The part opens fine in its default configuration, but when I change configurations it crashes Solidworks. I am able to edit the part just fine, but I cannot save it and get "An unknown error occurred while accessing..." even when I'm working on it locally. I cannot save a copy or "pack and go" the part. I can delete all the configurations, but that does not repair the issue with saving. I am working in Solidworks 2017, service pack 5.0. Does anyone have any suggestions for repairing the part?
