Error finding function on smart contract half of the time?

Question

I have a script that buys a token with multiple wallets, shows you a profit stream on the token, and then allows you to sell a set % of the token you have left before going back into the profit stream and repeating the process.

Everything works great 90% of the time, but randomly if I sell 50% of the token and go back into sell again, 1 of the wallets gets an error finding the sell function.

            try:
                amountToSell = round(walletTokens[address['wallet']] * percent / 100 )
                if chainNumber == 43114:
                    swap = router2.functions.swapExactTokensForAVAXSupportingFeeOnTransferTokens(amountToSell, 1, [contract, BNB], addresses[0]['wallet'], 1000000000000)
                else:
                    swap = router2.functions.swapExactTokensForETHSupportingFeeOnTransferTokens(amountToSell, 1, [contract, BNB], addresses[0]['wallet'], 1000000000000)
                tx = swap.buildTransaction({
                            'gas': config['sell_gaslimit'],
                            'gasPrice': sellGwei,
                            'nonce': walletNonce[address['wallet']],
                            'chainId' : chainNumber
                        })
                signed = web3.eth.account.sign_transaction(tx, address['secret'])
                web3.eth.send_raw_transaction(signed.rawTransaction)
                sellTransactions.append(signed.hash)
                walletNonce[address['wallet']] += 1
            except Exception as e: print(e)

This is the error I get. As you can see the first run both wallets sell. Then the 2nd run only 1 of them sells and the position arguments are all correct type.
