Was trying to use extensions---> modify paths---->prespective

I get the following error/not error.

Traceback (most recent call last):
  File "/usr/share/inkscape/extensions/perspective.py", line 171, in <module>
    Perspective().run()
  File "/usr/share/inkscape/extensions/inkex/base.py", line 231, in run
    self.save_raw(self.effect())
                  ^^^^^^^^^^^^^
  File "/usr/share/inkscape/extensions/perspective.py", line 126, in effect
    res = lin.solve(solmatrix, free_term)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "<__array_function__ internals>", line 200, in solve
  File "/usr/lib/python3/dist-packages/numpy/linalg/linalg.py", line 386, in solve
    r = gufunc(a, b, signature=signature, extobj=extobj)
        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/numpy/linalg/linalg.py", line 89, in _raise_linalgerror_singular
    raise LinAlgError("Singular matrix")
numpy.linalg.LinAlgError: Singular matrix

Any help in resolving this would be great.
