Actually, it is already dropped by the mempool I can't see the transaction he made on block hair so my guess is this transaction is already rejected by the mempool.
There is no such thing as "the" mempool. Just because one block explorer's node has dropped the transaction from its mempool does not mean any other node has followed suit.
@OP check your wallet again you might be able to create a new transaction
As nc50lc has said, OP's transaction is opted in to RBF so he can replace it any time he wants. And even if it wasn't opted in, full RBF is now widespread enough he could still replace it any time he wants with a little extra effort. He does not need to wait for any nodes to drop it.
