Here is a better picture of the damaged chain rail.
Here you could clearly see the broken pieces,,,with the broken piece it wouldn’tclip together causing a timing chain rattle noise.

So I had the timing chain replaced in my car and got it back today. It has not power and is throwing 3 codes, they are P13C9, P052B, and P13C0. Any advice on what would be causing this?

First I would take the car back who ever did the timing chain repairs,,,,second the faults are intake and exhaust vanos camshaft stuck and timing issues,,,,sounds like something they did wrong with timing the engine with the new timing chain.

So would the timing be causing the VANOS issue?

Yes it could be the problem,,,they have to take the valve cover off and time the engine,,,they can check the vanos at the same time,,,the timing and vanos unit work all together
