Particle IDE- Mysterious project importing issues

Hi all,
I (and oddly my partner for this class project) are having an identical problem with the IDE.
When we go into the GitHub folder to load project folders, we get one of two results:
either a) nothing loads at all, or
b) completely unrelated files are pulled up, without any file hierarchy on the side.

Additionally, any attempts to save changes to the random files that come up are unsuccessful and give the error message: “EEXIST: file already exists, mkdir”

Why is this happening, and to both of us?

Suppose you are talking about Desktop IDE, right?

Yes! Version 1.19.0, if that’s of any help.
