Well, it’s related to Mobile HDR or Mobile HDR + MMV (which I haven’t tested because I don’t see how people run apps on Quest without MMV). And it worked fine in 5.4.3 v68-v69 Meta fork. It doesn’t work in any of 5.5.x builds and it doesn’t work in 5.6.0 Epic (although it doesn’t crash - it just has no HDR effects).
So, no, I didn’t fix it. No one fixed it afaik.
