Hello,
This issue is a regression from 2021.3.7f1, hopefully, the fix is already in landing pattern, you can follow the resolution here (if you look at this only_renderer listing, you can notice gles is missing).
The Oculus Quest is an Adreno device which is expected to work with VFX but, for your awareness, it isn’t the case for most Mali GPU (more info here ).
Sorry for the inconvenience.
