I would suggest a new engine is cost prohibitive on a 2013 car.
There is a reconditioned one on eBay at the moment advertises for £3999 supplied fitted and guaranteed. No idea what the company is like.
There are others cheaper but not fitted.
It’s a sad fact that most garages can’t rebuild engines, so look for a motor engineers and see what they suggest. I had one rebuilt some years ago with a broken connecting rod they got away with a short engine and new valves. Rather than a full engine. It was still over 3k though and that was around year 2000.
As @BossBob says it will probably be damaged inside.
