Description of the bug

I’m running the example of assign_matrix on https://aedt.docs.pyansys.com/version/stable/API/_autosummary/ansys.aedt.core.maxwell.Maxwell2d.assign_matrix.html Set matrix in a Maxwell magnetostatic analysis. And the following error occured:

• PyAEDT ERROR: File "d:\A\test.py", line 14, in
  PyAEDT ERROR: L = m2d.assign_matrix(assignment=selection,matrix_name="Test2",turns=turns,group_sources=group_sources)

I've tried the other examples of assign_matrix(), and the results are all the same as mentioned above. Here are some version information:
PyAEDT INFO: Python version 3.11.9 (tags/v3.11.9:de54cf5, Apr 2 2024, 10:12:12) [MSC v.1938 64 bit (AMD64)]

Steps To Reproduce

from ansys.aedt.core import Maxwell2d
m2d = Maxwell2d(solution_type="MagnetostaticXY",version="2022.1",close_on_exit=True)
coil1 = m2d.modeler.create_rectangle([0, 1.5, 0], [8, 3], is_covered=True, name="Coil_1")
coil2 = m2d.modeler.create_rectangle([8.5, 1.5, 0], [8, 3], is_covered=True, name="Coil_2")
coil3 = m2d.modeler.create_rectangle([16, 1.5, 0], [8, 3], is_covered=True, name="Coil_3")
coil4 = m2d.modeler.create_rectangle([32, 1.5, 0], [8, 3], is_covered=True, name="Coil_4")
current1 = m2d.assign_current(assignment="Coil_1",amplitude=1,swap_direction=False,name="Current1")
current2 = m2d.assign_current(assignment="Coil_2",amplitude=1,swap_direction=True,name="Current2")
current3 = m2d.assign_current(assignment="Coil_3",amplitude=1,swap_direction=True,name="Current3")
current4 = m2d.assign_current(assignment="Coil_4",amplitude=1,swap_direction=True,name="Current4")
group_sources = {"Group1_Test": ["Current1", "Current3"], "Group2_Test": ["Current2", "Current4"]}
selection = ['Current1', 'Current2', 'Current3', 'Current4']
turns = [5, 1, 2, 3]
L = m2d.assign_matrix(assignment=selection,matrix_name="Test2",turns=turns,group_sources=group_sources)
