[New-bugs-announce] [issue40906] Unable to import module due to python unable to resolve dependecies

Hi,
I am building python ibm_db C extension for Python 3.8 support. while the binary is generated successfully and installed to site-packages, I am unable to load the same.
The error I get is:

Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:37:50) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import ibm_db
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed while importing ibm_db: The specified module could not be found.
>>> quit()

I have correctly set PATH and LIB to point to python installation. I have also updated LIB to point to correct runtime dependencies. 
Seeing through procmon, python is unable to resolve the runtime lib dependency path from PATH. The same steps work just fine for python 3.7 and other versions. This problem is only seen on windows. Linux and MAC works fine.

I am attaching the process monitor snippets for python 3.8(failing case) as well as python (3.7) success case.

Can you kindly look into it and share insights on what could lead to this problem and any possible resolution/s that are currently available. I tried with python 3.8.2 as same problem there as well.

Attached are the procmon logs for python 3.7(success case) and python 3.8(failing case).

python 3.7 : python3.7.log
python 3.8 : python3.8_1.log , python3.8_2.log
