It comes out crashed like the video below my VR app in ios version 14

However, when I rerun the iPhone, VR works fine.
So In order to solve it without re-running the iPhone, I tried installing the XR-plugin and gvr made by mobfish all failed.
I would be grateful if you could tell me how to solve such a case.
