I've been working with Tech Support to no avail. I have an issue where network mapped drives do not show up ANYWHERE. I've tried everything. All the uninstall/reinstalls. Wipe Esri registry files. All the things recommended by Esri and I still cannot see any mapped drives. Dragging and dropping does not work. Trying to connect with a path also does not work. I just get the following error:

Has anyone had anything like this happen? I can't even open a project on the network drive. I can't save a project on the network drive either. All the potential suggestions, I've tried. I'm at wit's end here.
