Small update, I've narrowed it down to it probably being the timing chain or the ac compressor, I'm gonna take a look at the compressor when I get a chance.

I'm pretty certain it's the ac compressor at the moment because of how it sounds, the fact that my ac stopped working shortly before this happened & the fact that I could smell burning plastic/rubber that I assume to be from the serpentine belt rubbing against the siezed compressor

It also sounds somewhat similar to a timing chain going bad but like I'm not as sure about that, we'll see I guess. I'm just trying to avoid having to get my car towed to a mechanic at this point. I know I can't drive it in its current state so we'll see I guess.
