Yep, I even found the reddit thread where OP responded to someone having the same problem as me. I'm going to try starting over again though so I'm hoping for a good outcome.
EDIT: I'm a fool. I had downloaded bluestacks 3 before so I assumed it'd work. When I downloaded the one in the link you provided, it worked. The only small problem I had was that I could not find microG service core, but upon reading your solution on reddit and disabling the google play services updates and reinstalling the apk, I was able to find it.
