Please help if anyone knows, I have a problem regarding com_error

Python

I am working on a project, which is in Python and Django. Whenever I try to select MS word file and upload it, the browser shows me this error.

com_error at /Review_page/
(-2147221008, 'CoInitialize has not been called.', None, None)

I have done all the things which were necessary like: created middleware files, applied middleware into the Django setting but don't know how to solve it. If anyone knows about it, any help will be appreciated.

What I have tried:

Here is the custom middleware.py file code which I have created:

import win32com.client
import threading

# Create a thread-local storage for the COM object
_thread_local = threading.local()

def get_com_object():
    if not hasattr(_thread_local, "Word.Application"):
        
        # Initialize COM based on the version of pywin32 
        if hasattr(win32com.client, "pythoncom"):
            win32com.client.pythoncom.CoInitialize()
        else:
            win32com.client.CoInitialize()

        # Create the COM object
        _thread_local.com_object = win32com.client.Dispatch("Word.Application") 

    return _thread_local.com_object 

class COMMiddleware:
    def __init__(self, get_response):  
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request) 

        # Uninitialize COM after the response is sent
        if hasattr(_thread_local, "Word.Application"):
            del _thread_local.com_object
 
            # Uninitialize COM
            win32com.client.CoUninitialize()

        return response

And here is the views.py file code:

def my_view(request):
    com_object = get_com_object()
    result = com_object.visible()

    return HttpResponse(result)
