Running newly installed inkcut on windows 10 fails to start

I've installed inkcut on a Windows 10 laptop using the instuctions on the website and when I run inkcut it fails with the following: -

File "C:\Users\Sandy\AppData\Local\Programs\Python\Python311\Lib\site-packages\enaml\core\code_generator.py", line 465, in insert_python_block
code = compile(pydata, self.filename, mode='exec')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: AST node line range (8, 1) is not valid

Has this been seen before?

I have added a text file with all the output from the command: -
incut error.txt

I'm getting the same message.... ValueError: AST node line range (8, 1) is not valid
