OBS Audio & Stream Troubleshooting

Whenever I open another application or overlay while Apex Legends is running, most of the lobby and game textures become pitch black for seemingly no reason. I have repaired the files through Origin, re-installed the game, changed my video settings, but the problem still arises every time. The attached pictures are the game after i open the Windows Overlay thingy by hitting the windows key while the game was open. This also happens when OBS is running in the background, which means I cant stream.
