Box Projection doesn’t work with Unity 2019 build-in pipeline and single pass stereo rendering on Oculus Quest.
There is no problem if I build the exact same scene with Unity 2018.
Does anyone have the same problem?
Have you tried Unity 2020 or alternative projector assets? The projectors coming with Unity are very intensive, maybe you can kill 2 birds with one stone, when switching to either Unity 2020 or an alternative projector.
Do you use single pass stereo in 2018 as well? Maybe you can look at this shader tutorial. It is about how to make shaders work with single pass stereo rendering:
If these things don’t help you might have found a bug. It would be great if you could submit a bug report in that case 
I’m sorry I didn’t have enough words.
It means Reflection Probe Box projection.
