Type Error due to environment variable and ganache

[Amandeep404]

Hey can someone help me...I am facing the same issues on windows as many are facing but unable to correct it.
Shows the same error as everyone else here :

in sign_transaction
    raise TypeError(
TypeError: from field must match key's 0x090dC592fDF4d7adB16CCCf15262335DE66eD316, but it was 0x7052b17De0ccc1De68437b03b197bF3057E45807

This happened when i closed the ganache and terminal and when i came back to work on this project its showing this error

Here is the whole deploy.py file

from solcx import compile_standard
import json
import os
from web3 import Web3
from dotenv import load_dotenv

load_dotenv()


with open("./SimpleStorage.sol", 'r') as f:
    simple_storage_file = f.read()

compiled_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {
                    "*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]
                }
            }
        },
    }
)

with open("compiled_code.json", "w") as f:
    json.dump(compiled_sol, f)

# get bytecode
# this is iterating through the compiled_sol.json and getting the bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"]["bytecode"]["object"]

# get abi
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]

#for connecting to ganache
w3  = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545"))
# print(w3.eth.chain_id) # This is the chain id of the ganache network which returns 1337
chain_id = 1337
my_address = os.getenv("My_ADDRESS")
private_key = os.getenv("MY_PRIVATE_KEY")

# Create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
print(SimpleStorage)

# Get the latest transaction count i.e nonce value
nonce = w3.eth.get_transaction_count(my_address)
print(nonce)

# Create the transaction
transaction = SimpleStorage.constructor().build_transaction({"chainId": chain_id, "from": my_address, "nonce": nonce})  
signed_txn = w3.eth.account.sign_transaction(transaction, private_key=private_key)

# Send the raw transaction
# tx_hash = w3.eth.send_raw_transaction(signed_txn.rawTransaction)
# tx_reciept = w3.eth.wait_for_transaction_receipt(tx_hash)

# working with the contract
        #for that we need contact address and ABI
# simple_storage = w3.eth.contract(address=tx_reciept.contractAddress, abi=abi)
# Call -> Simulate making the call and getting a return value
# Transact -> Actually make a state change

print(w3.eth.get_balance(my_address))
print(my_address)
print(private_key)

And this is my .env file

export MY_ADDRESS ="0xb117deF084176e5Fdac7d979aa6524e3c8282049"
export MY_PRIVATE_KEY ="0x31792fce4b6f6408398f3d73f8b2f438b44c515fffd576eee1766463ecdf7c93"

Help will be Appreciated !!

pls make sure your using correct private key ,, I guess this is issue
I think some thing is wrong in "from" field in using private key ,
please notify is it usefull or not
