Game Cropping In Build But Not In Game View

Hey guys!

So I've been struggling with this issue for a week or so now. When playing my Unity builds (or any that are sent to me), Unity crops the top and bottom of the screen (black bars). I have attempted to track the issue down in the build settings for several hours with another creator to no avail.

The first pic is how the game looks in Unity in the scene view (how I want it to build) while the second is what I see when running the build. This game used to play fine in the past and did not feature the crop, but is now being affected same as my other builds.

Any guesses about what might be causing this issue and how I can go about resolving it? I work primarily with Unity version 2019.2.2f1 and 2019.2.5f1. Thank you!
