Unable to parse valid xml in cpython 3.8 - python-3.x

Question

I'm trying to parse xml file in Python script, which is working inside the C++ application. When I'm trying to run this script:
import xml.etree.ElementTree as ET
root = ET.parse('somexml.xml' ).getroot()
I always receive an error:
RunScriptFail: Traceback (most recent call last):
File "xml\etree\ElementTree.py", line 1500, in __init__
File "<frozen zipimport>", line 259, in load_module
File "xml\parsers\expat.py", line 4, in <module>
ModuleNotFoundError: No module named 'pyexpat'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "xml\etree\ElementTree.py", line 1503, in __init__
ModuleNotFoundError: No module named 'pyexpat'
During handling of the above exception, another exception occurred:

File "xml\etree\ElementTree.py", line 1505, in __init__
ImportError: No module named expat; use SimpleXMLTreeBuilder instead
Error parsing script
But pyexpat.pyd exists in lib folder of cpython. How can I fix it? Or may be I can use some workaround for it?
Solution from Using SimpleXMLTreeBuilder in elementtree works for me

I found that needed pyexpat.pyd is not copied into distribution. I added it ad that resolved my issue
