Did you try to copy and paste the the path, or drag and drop it? Can you post a screenshot?
Could you please post a screenshot taken at View > 100% and with the pertinent Panels (Layers, Paths, Options Bar, …) visible?
After I saved the workpath I lowered the resolution of the image and was then able to export Paths to Illustrator. So it seems those are somehow connected. But it seems odd as the path stays the same after lowering the resolution.

Changing an image’s resolution does not affect its dimensions as measured in mm or inches but in pixels but the number of pixels.
And as Paths are not pixel content but vector content it hardly matters on those, as they maintain their dimensions, too.
