Are you using the latest version of Bitcoin Core?
Can you share the receiver's address here and the address where the bitcoin comes from?
Some block explorer doesn't recognize any transaction with low fees like blockexplorer.com according to this post (https://bitcointalk.org/index.php?topic=2751577.msg28109248#msg28109248).

I don't have much knowledge on using this wallet but let me try to help you.
I found some old post here that I think will help you to remove the transaction and make a new one instead.

Follow the guide below.

You can manually remove the transactions from Bitcoin Core:
-Exit Bitcoin Core
-Backup your wallet.dat, even though you should have a backup already, make another backup
-Start Bitcoin Core from a command prompt with options -zapwallettxes -rescan (if you're using a pruned wallet, you can't use this)

Depending on your hardware, it will take a few hours to rescan. After this, your transactions should be gone, but Bitcoin Core might pick them up from mempool again. In that case just wait for it to drop again.

Full description of the commands:
Code:
  -zapwallettxes=<mode>
       Delete all wallet transactions and only recover those parts of the
       blockchain through -rescan on startup (1 = keep tx meta data e.g.
       account owner and payment request information, 2 = drop tx meta
       data)
Code:
  -rescan
       Rescan the block chain for missing wallet transactions on startup

Did you launch the wallet with -walletbroadcast=0? If yes, then you should launch it normally without any arguments as the wallet won't broadcast any transactions to the network and your transactions won't be seen by others.

You can follow BitMaxz advice and launch it with -zapwallettxes which will remove all the unconfirmed transaction. You will have to wait for the transaction to be dropped by the nodes around the network and you can send a new transaction.

As i think -walletbroadcast=0 sets automatically if i set -blocksonly=1 in bitcoin.conf.

How will be better and faster - run without -walletbroadcast = 0 or run witn -zapwallettxes?

If you want to use CPFP, run without walletbroadcast=0. If you want to just remove it completely, use -zapwallettxes.

Either option will work; CPFP will cost slightly more and it would take less time while retaining the same transaction, zapwallettxes will take some time (for the transaction to be dropped from mempool) and it wouldn't cost more to send again.
