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)

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

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
i will try google now, ofc

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
