Objects.requireNonNull(ctx.get().getSender())

there is no sender on the client, due you sync your capability to all players you have to send the associated player's network id to the client
then you can get the Player on client side via ClientWorld#getEntityByID

you also need to note that Packets whach are sent from the server to the client should be handled in another class and wrapped via DistExecutor#unsafeRunWhenOn
you can take a look at this as an example (the second code part)

ClientWorld#getEntityByID

mmh how to use it? sorry im so stupid

it's a method you should call it you can get the ClientWorld from:

Minecraft.getInstance().world

i can't, i just don’t understand where to put it

You should only send the packet to the player actually owning the capability. There is no reason to distribute it to all nearby ("tracking") players, let alone all players.

but all of the players owning this capability

and how to send this packet only for players that owning that cap?

sorry, but i'm still don't understand how to get player that owning my capability

Pass it as a constructor parameter to your capability instance.

how....

if you don't know how to pass in a parameter to the constructor and storing this parameter in a final field
you should learn basic java first

the problem is that im russian, and most likely it sounds different in my language, so i don't understand what you are talking about. sorry
