AttributeError: module '_libheif_cffi' has no attribute 'lib'

[M4R0N9]

When, after many difficulties, I managed to install pyheif and libheif, I got the following message: AttributeError: module '_libheif_cffi' has no attribute 'lib'. I will add that the _libheif_cffi.pyd module was originally in the main modules folder, but loosely, so it was not visible at all, only when I moved it to a created folder with the same name it is visible to Python, but it has a problem with the lib attribute . What can I do in such a situation?
Here is the entire cmd entry:
Traceback (most recent call last):

I am attaching the module I am writing about:

_libheif_cffi.zip

I see you made an almost identical post over at carsales/pyheif#94 which is probably a more appropriate place.
