Blank Screen in BGE After Installing Nvidia GPU

I recently switched out my AMD card for Nvidia because I was having some issues with my previous card and I decided to go Nvidia for once. To my dismay, when I went to work on a game I’ve been working on for months, pressing play just reveals a completely blank screen. I can hear audio, and I know the game is working, but I can’t see anything except the background color, which in my case is black. Now here’s the weird part, if I go to my HUD scene and press play, I can see everything just fine. It’s only the view in my main scene that is blank.

I removed the old AMD drivers completely before installing the Nvidia ones, so I’m quite sure that isn’t the problem. I’ve been playing games just fine. So, does anyone know what could be causing this? I’ve been trying to figure it out for a while now. :frowning:
