Based on that transaction it has a large number of outputs including small BTC so I think whoever made it doesn't know how to consolidate the transaction.
He sent only 0.01088549BTC why he didn't just choose one output with that amount to send and pay the fee less than the fee from this transaction. It has 750+ outputs which is one of the reasons why he pays a large fee just to send a small amount.
I'm sure this is a newbie he doesn't know how to consolidate the transaction to get less transaction fee in the future.
But the guy's transaction was at a fee rate of 5,187.2 sat/vByte. Sincerely even if it was a newbie, What Kind of evil wallet suggests 5,187.2 sat/vByte? He sent only 0.01088549BTC why he didn't just choose one output with that amount to send and pay the fee less than the fee from this transaction.

400 or 500 sat/vbyte would be understandable even in times of high fee rates.
