Joblib giving error when loading my model

Question

I am trying to build a project, where I will get the data from the webpage and it will be passed to my ML model, the predictions of which will be shown finally. The model is completed and I have it in the .sav - named as "litemodel.sav" and below is the code for the same.

Below is the text snippet of the error that I am getting. Since there isn't a description attached to it, it is getting difficult to debug. Anyone encountered a similar issue?

Traceback (most recent call last):
  File "E:\__COURSE IIT\XYZ\ROAD\main.py", line 10, in <module>
    model = joblib.load('litemodel.sav')

Below is the code producing the error:

from flask import Flask, render_template, request
import pandas as pd
import numpy as np
import urllib.request
import urllib.parse
import joblib

app = Flask(__name__)
model = joblib.load('litemodel.sav')

[1. joblib is installed in the system (I have checked it - below is the text snippet confirming it) ]

PS E:\__COURSE IIT\XYZ\ROAD> pip install joblib
Requirement already satisfied: joblib in c:\users\mitta\appdata\local\programs\python\python312\lib\site-packages (1.3.2)

UPDATE

Below is the new error (should I get my python to lower version?)

File "E:\__COURSE IIT\BTP\ROAD-ACCIDENTS-PREDICTION-AND-CLASSIFICATION\main.py", line 10, in <module>
    model = joblib.load('litemodel.sav')
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

ValueError: You may be trying to read with python 3 a joblib pickle generated with python 2. This feature is not supported by joblib.

How to resolve this?
