Mobs freezing

While playing multiplayer survival, after some time I realized the cows in the farm started freezing when I went closer to them, I could breed, leash, kill them, everything possible, but they were just frozen in place then I had to rejoin to come back to them moving again, and this kept happening. Later it started happening to other mobs too, like Pillagers, pigs, tamed horses, tamed wolves. when I went closer (sometimes) they just froze. Later I went in my own world to see if its just a multiplayer glitch but then it started happening to me in the nether with Piglins, they showed as standing in place and when I hit them and went away from them my health was getting lower but they were standing in place and this was right after I got the 1.16.100 update but now it started to happen more often, and sometimes Im not even close to them, I just see them from a distance and they freeze. Hopefully this info helps, I wrote as much as I remember.
