P2PWKH to P2PWKH [non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation)]

Hi, I'm new to Bitcoin and can't figure it out.

sender_priv_key = PrivateKey.from_wif(
    "92X8vyMDfHbip7K1N4ATFyHFsPxjx3GadmCi51wsmT4KXCpbc5q"
)
sender_pub_key = sender_priv_key.get_public_key()

receiver_addr_1 = P2wpkhAddress("tb1q3w2u9k99xfchpf2eu5ut8fnk7xhfn905h5s3lu")

script_code = Script(
    [
        "OP_DUP",
        "OP_HASH160",
        sender_pub_key.to_hash160(),
        "OP_EQUALVERIFY",
        "OP_CHECKSIG",
    ]
)

# 2000 satoshi
txin1 = TxInput("570ab331d50cf5b0a91b7dd4a8abfaee07dee23853083f32de981eed4a9f7f04", 1)

#  512 satoshi
txin2 = TxInput("1899c7e991676095152d8daf8820892fd8c1c401f64295882f311dfafaff01d9", 1)

# 420 satoshi left for transaction fee
txout_1 = TxOutput(2000 - 420, receiver_addr_1.to_script_pub_key())
txout_2 = TxOutput(512, receiver_addr_1.to_script_pub_key())

tx = Transaction([txin1, txin2], [txout_1, txout_2], has_segwit=True)

txsign1 = sender_priv_key.sign_segwit_input(tx, 0, script_code, 2000, SIGHASH_ALL)
tx.witnesses.append(TxWitnessInput([txsign1, sender_pub_key.to_hex()]))

txsign2 = sender_priv_key.sign_segwit_input(tx, 1, script_code, 512, SIGHASH_ALL)
tx.witnesses.append(TxWitnessInput([txsign2, sender_pub_key.to_hex()]))

print("Raw transaction size: ", tx.get_vsize())
print("TxId:", tx.get_txid())
print("Raw signed transaction:\n" + tx.serialize())

When running the script and sed raw tx to node, an error is thrown:

error code: -26
error message: non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation)

Alternatively, I tried signing the transaction via cryptos and it worked fine. I would be very grateful if you help me with the answer!
