Getting fps drops & lag spikes randomly on offline single player worlds

I don’t know if this is also affecting players on other devices, but recently, when I’ve been playing on any of my offline multiplayer worlds (old and new worlds), I’ve been getting these these occasional, random fps drops and lag spikes out of, and it’s been happening regardless of my graphic settings nor my render/simulation distance, and I have a good device that’s pretty good at running Minecraft and I’ve only recently been experiencing this.

Hope this gets fixed soon cuz it’s really annoying.
