First of all, I would like to congratulate you on this wonderful work.
In the FreeCAD dev (0.22 and more) the methods named __setstate__ and __getstate__ have been renamed to 'loads' and 'dumps', due to a conflict name since Py 3.11.
This have been published in the FreeCAD App: Fixe #10460
The error message when saving the FreeCAD file is like this:

We already found this bug in another addon (Fastener addon issue #297) and I made a patch for it (Fasteners pull request #302).
I will soon make a Pull request for patching the Curve Workbench...
