Odd Green lens flare artifacting when rendering at 4k

I’m trying to render out a sequence in 4k but I keep getting these blown out green lens flares on some frames. Has anyone encountered this? I’ve read about motion blur issues or post processing issues? It only happens when I render at 4k though. Any solutions or suggestions welcomed. thank you!


What version of UE5 are you using?

I have seen this in the lumen thread.
It’s related to Lumen just don’t know how.
