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 of this transaction to 20,000 sat/vbyte.
Since you say you tried different servers and none of them allowed you to broadcast the replacement transaction, one solution is to export the raw transaction data, broadcast it using other tools and see of 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 CPFP transaction manually and spend the fund from bc1qkxy0p5vdve4jsv5f8mgfds75m4tqcq8dq0nawr 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 of the other transaction to 20,000 sat/vbyte and it would increase the effective fee rate of your transaction to 35.5 sat/vbyte which is insufficient for getting fast confirmation.
Take note that you have already spent $480 worth of bitcoin for doing CPFP and you will spent another $480 worth of bitcoin for making another CPFP transaction or increasing the fee rate of your current CPFP transaction.
