HELP! Game breaking visual bug

Development Programming & Scripting Blueprint

Hi everyone, looking for some urgent help with this bug. I recently started testing packaged versions of my game. On my computer, things work perfectly fine (shocking I know), however when playing the exact same build on a different computer (with the same in game settings), this horrific visual bug happens.

How it should look (my computer)

How it looks on the other computer (mind you, a better computer)

For reference, my specs:

Windows 10 64-bit
AMD Ryzen 5 1600
48gb RAM
DirectX 12
GeForce GTX 1070

Problem computer specs:

Windows 10 64-bit
AMD Ryzen 7 7700X
32gb RAM
GeForce RTX 3080

I have absolutely no clue why this could be happening. My best guess is it has something to do with Unreal prerequisites? I have b.IncludePrerequisitesInstaller disabled in the project settings, so could the bug be from an uninstalled prerequisite?

Looks like a reflection being cast onto the wall. Do you have a reflection capture there?

Try on other setups.
Could be driver issues.

I’m not much of an expert myself, so I can only offer wild guesses; but, do you perhaps have a second camera in your level? Maybe attached to a component in your player BP and invisible in your viewport…
