ERROR Python: Traceback on one file only

[fitaine]

My file was working fine and then I started to get an error when I tried to refresh sketches or add constraint to it. I think it has already happened to me previously but I was going back with a Ctrl+Z and it sorted things out. This time I may have not try to refresh the sketches for a while and didn't see the issue immediately, so it was impossible to going back.

• Blender version is 3.6.9
• CAD_Sketcher version is 0.27.5
• No problem on other .blend files
• Link to the problematic .blend file : https://transfert.free.fr/rX6U9Pw

Here is what I get:

Python: Traceback (most recent call last):
  File "/Users/Tiphaine/Library/Application Support/Blender/3.6/scripts/addons/CAD_Sketcher-main/operators/solve.py", line 18, in execute

I hope someone could help me on this one, because I spend some time on it. I really like to understand what I did that led to this problem.
