Mobs freezing every couple seconds after creating new world

as you can see in the videos provided, in all my worlds since i creates this new one the mobs freeze for a second and continue and there is no way to stop it. I restarted my Nintendo switch, restarted the game multiple times, deleted worlds made new worlds, tried airplane mode, tried online, tried lowering the settings… everything. Nothing works. Please help. I had to cut the videos down for the upload but you can still clearly see what I’m talking about. This only started after creating a new world today and now it wont stop in any of my worlds.
