Solved it! Because no one answered for a day, I had posted in the Forums, where Tim Hobson realized what was wrong. (Eye Adaptation and Screen-Space Reflections not working on my computer. - Rendering - Epic Developer Community Forums)
My work computer has a slightly older graphics card, and I didn’t realize that Unreal Engine modified it’s graphical settings based on how much your computer could theoretically handle. Under the quick settings, I had to change the Engine Scalability settings back to high. It was only previewing what would be available on weaker platforms.
