[philippe] > It seems to be a conflict with phyton version (getargspec seems to be > depracted)
Thank you for discovering this problem. :) While I doubt 'grave' is the correct severity for this, as it do not render FreeCAD completely useless that one of the workbenches do not work, and I personally is using the Part Design and Part workbenches with success, I can reproduce the issue and the problem seem to be due to python version incompatibility. The method is present in Python 3.8[1], but not in 3.11[2] used in Debian at the moment. Only the recommended replacement getfullargspec() is present in 3.11. This issue need to be fixed upstream, as it is also present in version 0.21.
