when I destroy a block in a server of one of my friends, Minecraft doesn't give it to me, it just disappears, it doesn't produce any sound when I punch any block, I also cannot damage any mob and hostile mobs don't do anything to me, they don't even follow me.

meanwhile, my friends can play normally. I cannot damage them and the world doesn't load for me, here is some evidence of this.

it's not my internet connexion. because I can see them moving around and they can see me too, they also can see and hear that when I destroy a block, the block doesn't make any sound and it doesn't give it to me.

this ONLY  happens in this world, it doesn't happen in the world of other friends or in personal worlds, my other friends can play normally, but i can't.
