Random Tall Flashing Beams in the Sky

I have been playing on a 1.21 Survival world since nearly the beginning of this year, and up to about a month ago I had these tall flashing beams come out of nowhere. I thought maybe this might have been a bug when applying experiments to the world, yet I loaded up a brand new creative and survival with no experiments and no cheats and the flashing beams are still there. I stopped playing for a few weeks assuming that maybe a bug update would release and fix this issue yet nearly a month later I still have them. I have provided images down below hoping the can be beneficial
