Maybe Windows 10 VM understood the ctypes.util, on mine it was complaining that there is not util attribute in ctypes and I asked chatGPT and chatGPT gave me that from ctypes.util import find_library code which works
Not sure why it would blow up on me i mean it's the same thing (to me).
Ah I noticed you attached a file rich and looked at it and for windows it's also doing the from ctypes.util import find_library so that would work (strange how that is to me).
There is a problem with the version I put in post #4, I only have Linux so didn't realise. I think changing just the import statement should fix it. If any Windows users could try the one below and say if it works that would be helpful. Thanks.
