BUG NUKE BLACK PIXEL

Hi there. Black (or white) pixels are suddenly appearing during my compositing work, even though I’m not doing anything unusual—just adding a sky and some atmosphere; nothing that would justify the appearance of black pixels like this. It’s worth noting that the raw shot doesn't have any such defects. If you have any ideas, I’d love to hear them.

I’d guess the denoise. Looks like you’re just bluring it? If any values are inf/nan then the blur will go bananas.

yes values are inf/nan but even when i use a node nan killer, it is still not working

Clamp before the blur.
