Mod Manager Unable to Pack Any Mod

Hi y'all,

I recently finished a basic skin mod and tried to pack it using the mod manager, but it keeps telling me that it can't pack it because doesn't exist:

The current directory for my mod follows Beam's tutorial instructions:

\BeamNG.drive\current\mods\unpacked\BurgerRing\vehicles\etkc\BurgerRing\(My skin files)

I also tried downloading a mod from the repo, unpacking it, then immediately packing it, and was met with the same not-existing error.
