Quest Single-Lens blackscreen world bug/error

I’ve been working on VRChat worlds for a while now, but recently I’ve noticed something in one of my quest-compatible worlds. When on PC, the world is perfectly fine, but on quest, the right lens completely turns black, but the world still shows though the left.

What is this caused by? and more importantly, how do I fix it?

This is probably because you are using a shader that Quest does not support.
