League of Legends Update Causing FPS Drops

Since the recent updates, I've been experiencing severe FPS drops in League of Legends, sometimes even hitting 0 FPS. There were no issues in Teamfight Tactics, but after the update on May 13, 2024, the same FPS drops started happening there as well. I've tried all the solutions I could find online, but nothing has worked. I don't believe it's related to my hardware (RTX 2060, 3300X, dual 8GB RAM, 100GB free space, no ping issues). I've tried different resolution settings and everything else, but the problem persists. Other games run perfectly fine without any drops.
