I was having nothing but problems trying to export even a simple file to DWG or DXF format. had tried everything I could think of, until I finally tried to change the destination folder - previously I was trying to use a subfolder under my OneDrive's folder on a Windows machine, everything just gave back an error 2067 (which I assume is a generic error from the AutoCAD libraries Adobe must use here, since a lot of people get it importing/exporting/etc) but then I just tried saving the desktop, voila 🤷:male_sign:
