Chosen Solution
So I just bought and replaced the back panel for the Pixel 4, everything works just fine except the camera. Now it’s fully blurry, not like, smoky or anything, it just refuses to focus. I am really hoping for a fix to this without needing to purchase anything else, but at this point, I would love any knowledge on the matter.
Nevermind. I am an idiot, and didn’t take off well marked protective stickers from the back of the plate.
