So, you made a CPFP transaction with the fee rate of 10,046 sat/vbyte and the total fee of 0.011 BTC.
Now, you want to bump the fee rate of this transaction to 20,000 sat/vbyte.

Since you say you tried different electrum servers and none of them allowed you to broadcast the replacement transaction, one solution is to export the raw transaction, broadcast it using other tools and see if they allow you to do so.

Here are some broadcasting tools.

The other solution is that you make a new CPFP transaction instead of bumping the fee of the previous one. Note that in this way, you will add another unconfirmed transaction to your wallet.
To do so, you need to make the new CPFP transaction manually with spending the fund from bc1qkxy......... to one of your own addresses.
If you make this transaction with the fee rate of 10,000 sat/vbyte, it would have the same effect as bumping the fee rate of your CPFP transaction to 20,000 sat/vbyte and it would increase the effective fee rate of your transaction to 35.5 sat/vbyte which is still insufficient for getting fast confirmation.

Take note that you have already spent $480 worth of bitcoin for doing CPFP and you will spend another $480 worth of bitcoin for making another CPFP transaction or increasing the fee rate of your current CPFP transaction.
Also note that you may need to use coin control, if you have other funds in your wallet and you want to make a new CPFP transaction manually.

Hi,

I appreciate the time you took to write this.

We need that funds for urgent project and yes we want to sped another 480$ on fee.

We have already performed the CPFP inside electrum and it doesn't give us the option to create another child transaction only to increase fee which seems impossible to do it above 10k sats

We have Confirmed coins inside the wallet and we have a doubt that this may Affect other coins, and block the entire wallet.

We have tried to to use the Hex after signing the transaction and all these websites return the message code 25 Maxtxfee.

Thank you again for the response.
