SHAPER - Error: Chamfer algorithm failed

SALOME V9.14
Windows 11

Hello!
I am drawing a 2" plate.
If I try to do a chamfer with length 2" and 45° angle, the following error appears:

Error: Chamfer algorithm failed

If I change the lenght to say 1.99", it works properly, but it’s not what is needed.

Is this a bug or am I doing something wrong?
