TypeError: cannot pickle 'pyodbc.Cursor' object

I am using pickle in my ML model loading, Not sure how to troubleshoot this error, how the pickle loading is connected to X_com, I stopped using Xcomm in code as well, even though I am getting the pyodbc.Cursor error. I am using pyodbc for my database connectivity check
