“Operating system is not presently configured” error with Access ODBC

I get the following error when I try to connect to Microsoft Access Database via Python. The code has been working all this time and only started popping the error today. Can someone please guide me what may be the problem occurring now?

I tried doing this https://stackoverflow.com/questions/63899661/operating-system-is-not-presently-configured-error-with-access-odbc  even after removing the “Office 16 Click-to-Run Extensibility Component 64-bit Registration” my problem isn't getting solved.

import pyodbc as pyo 
import os

#print(pyo.drivers())
filename='//MCISERVER1/TestData/access/Proof.mdb'
full_file=os.path.abspath(os.path.join('data',filename))
print("opening access")

Driver='{Microsoft Access Driver (*.mdb, *.accdb)}'
access_driver=['MS Access Database']

try:
     cnn=pyo.connect(driver=Driver,dbq=full_file,autocommit=True)
except pyodbc.Error as ex:
     print("Error connecting")

cursor=cnn.cursor()
sql="select * from [ERT ITRON] as e where e.SO='7888'"
cursor.execute(sql)
for row in cursor.fetchall():
    print(row)
print("success")
cursor.close()
cnn.close()
print("connection closed")
