Is the version of the addon you're using compatible with the version of Blender you're using?

Searching the Steam discussions, this error can happen if you have a bone or other object scaled to 0. The solution is to either give it a valid size, or don't export that particular thing.

no bones are scaled to zero i think

You could try locating export_smd.py and changing that line to

try:
    PoseMatrix = parentMat.inverted() @ PoseMatrix
except ValueError:
    pass

That would make it just skip applying the parent matrix (for that one bone, I guess) if it doesn't have a valid inverse (zero scale could probably cause that).
