For anyone in the future having the same problem, I have fixed the issue:
I had to turn off both Mobile Multi-View and Vulkan.
Turning off mobile multi-view caused the whole project to recompile the shaders, however. Also, FPS is at the red (50-60 fps). When it was working, Vulkan being on kept it at 72fps.
I need a solution where Vulkan is on, or have the FPS at 72 without Vulkan.
