Game constantly freezes every 30-60 seconds

So, while I’m trying to play my Minecraft hardcore world, every 30 to 60 seconds the game will just completely stop. And when I’m riding an entity (i.e. boat, horse, etc), it just teleports ahead randomly without being able to turn. This is especially frustrating as I keep falling off tall ledges or into deep water while I’m riding my horse through the world.

I have done everything I could to try and stop it, including deleting resource packs, lowering render distance, changing graphics from fancy to simple, but nothing works.

Sorting this out asap will be greatly appreciated. Thanks.
