wst can you reproduce on v0.20 dev? https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds

I can't reproduce, no forum post and no further comment from OP -> should be closed IMO

I experience the same error when redundant constraints are present. Resolving the redundancies first solves the issue.
