I used python-bitcoin-utils Python tool to generate the following code related to the transaction ID 88558b495f28ff4799a4dacf40ee5cd1666850fed4847b8315256a5ae22527f8 which involves inputs from both P2TR and P2WPKH scripts.

def main():
    print(to_satoshis(0.0000022))

    setup('testnet')
    priv1 = PrivateKey("cV3R88re3AZSBnWhBBNdiCKTfwpMKkYYjdiR13HQzsU7zoRNX7JL")
    priv2 = PrivateKey("cSfna7riKJdNU7skpRUx17WYANNsyHTA2FmuzLpFzpp37xpytgob")
    pub1 = priv1.get_public_key()
    pub2 = priv2.get_public_key()
    fromAddress1 = pub1.get_taproot_address()
    fromAddress2 = pub2.get_address()

    vout2 = 1

    amount2 = 100000
    amounts = [amount1, amount2]
    script_pubkey1 = fromAddress1.to_script_pub_key()
    script_pubkey2 = fromAddress2.to_script_pub_key()
    utxos_script_pubkeys = [script_pubkey1, script_pubkey2]

    toAddress = P2pkhAddress('mnv5EAfPMTbfatz5ZbT6uUKpK7E5MftBAv')
    txin1 = TxInput(txid1, vout1)
    txin2 = TxInput(txid2, vout2)
    txOut = TxOutput(to_satoshis(0.0000022), toAddress.to_script_pub_key())

    tx = Transaction([txin1, txin2], [txOut], has_segwit=True)
    sig1 = priv1.sign_taproot_input(tx, 0, utxos_script_pubkeys, amounts)
    sig2 = priv2.sign_segwit_input(tx, 1, script=script_pubkey2, amount=amount1)

    tx.witnesses.append(TxWitnessInput([sig1]))
    tx.witnesses.append(TxWitnessInput([sig2, pub2.to_hex()]))
    print("\nRaw signed transaction:\n" + tx.serialize())

I'm constructing a script to spend multiple distinct UTXOs in a single transaction. I've successfully combined all UTXOs except for two.

Succeeding in spending a P2TR with P2PKH UTXO.

I encountered a problem when attempting to spend a P2TR with one of them P2SH, P2WSH, P2WPKH.

accompanied by a 'non-mandatory-script-verify-flag (Invalid Schnorr signature).

While I managed to dispatch these transactions via an alternative node, none of them have been confirmed as of yet.

tx ids: (bitcoin-testnet)

88558b495f28ff4799a4dacf40ee5cd1666850fed4847b8315256a5ae22527f8 02429ffe2f82f587d8e7a6e925201d3e7f219ac3af3688f2bc5c2770204e5d5c

What could be the cause? thanks
