Sorry to hear you’re still struggling!
Have you tried starting from fresh with a new image of Pi OS Bookworm and a fresh pull of the library? We’ve now merged in all the updates to accommodate the new GPIO libraries and updated our Learn guide so things should hopefully now be in a less confusing state than they were back in April.
If you’re still having problems getting things working please let us know the exact text of the errors that you’re getting and we’ll see if we can help further.
