Unfortunately it looks like, that's only possible with mixin/core modding (which is not supported on this forum)

you can create a LevelCapability which stores your inventory (use Forge IItemHandler). Then create a menu which you can open for example with a custom KeyMapping. Note you need a custom Packet when you want to open the Menu from the client. Also you need to sync the Inventory to all Players which has open it (look at the ChestBlockEntity for an Example)

did you use MCreator for modding?

post new debug log

you can find it in .minecraft/launcher_log.txt

use the other Constructor

if you use 1.17 it's called CreativeModeTab

sever and client, but if i'm correct the ItemGroup is only use for sorting in creative (so client)

post debug log

delete this client config

only the folder, since a mod creates a config file in this folder but they forgot to create the folder itself that's why you get the error

depends on the minecraft version you are using 1.18 - Java 17 1.17 - Java 16 all other versions required Java 8

the problem was fixed in 1.18-38.0.2, update forge

show your Entity class and your registration

I will look at this, and try to find a solution for your problem

if you have a git repo post a link to it, if not post the relevant classes

you will find it in .minecraft/logs/debug.log and you could post it via https://gist.github.com/

its an know issue, but unfortunately I can't tell when the issue will be fixed

I would recommend you to add custom models manually, since it's easier than use Data generator

The crossbow does not use a custom Renderer, it only use a few models. Did you looked at the vanilla models?

use the java installer, why did you need the windows installer

yes

you need to create your own LiquidBlock, copy the vanilla code and replace all code which use the vanilla Field with LiquidBlock#getFluid

you can get a Player in client Events via Minecraft.getInstance().player Note: this only works in client Events
