I was driving around yesterday when I stopped at a red light and the engine stalled, I tried to start it back up but it just wouldn’t and had to wait 5 minutes before it worked again but now theres a knocking sound and the car is undrivable at this point as it will stall as soon as I come to a stop, the knocking is really loud and it increases as I accelerate. Any idea what it might be? Thanks

It’s probably too late for this advice now, but:
Check the oil level on the dipstick. Is it (very) low?
I think I see the red oil pressure warning light is on. Was that on while you were driving?
when the rpms dropped the oil light came on, but when I accelerated it turned off. oil level on the dipstick is fine
OK. That makes it *slightly* less likely it’s rod knock. (Because rod knock is often caused by low oil or low oil pressure.)
If it were my car, I wouldn’t scrap it (or replace the engine) quite yet. I would cross my fingers, remove the serpentine belt, (or even cut it off, because you have nothing to lose), and start the engine. If the knocking disappears, breathe a great deep sigh of relief, because it’s nothing internal to the engine, just a failed harmonic balancer or something. (But stop the engine after a minute or two, or it will overheat, without the serpentine belt turning the water pump.)
But don’t get your hopes up too much.
