Ctypes: Why WinDLL(library) doesn't work and WinDLL(find_library(library)) does?

Question

I'm working with an external wrapper that loads a dll in python. They use the below:

from ctypes import *
_lib = WinDLL(library)

However, I'm getting the error:

FileNotFoundError: Could not find module 'vcmowr64' (or one of its dependencies). Try using the full path with constructor syntax.

The dll is in the same directory as all the python files being used. The odd thing is that if I use the below, the code works:

from ctypes import *
from ctypes.util import find_library

_lib = WinDLL(find_library(library))

I don't understand why. I imagined that find_library function had same logic to find the dll as the WinDLL.

I'm using Windows 11 Enterprise and python 3.11.
