I've been running SW 2019 for months now and today it decided to give me the below error message when I try to do a pack and go. I do pack and goes (packs and go?) maybe 20 times a day. now I am getting this.

I am just doing a pack and go to within the same folder, just renaming it and keeping the original file as is. this is now happening with model files and well as drawing files.

Any Thoughts?
