post debug log

post debug log

this is the launcher log, the debug log is in .minecraft/logs/debug.log if you playing on CurseForge you need to enable the debug log in the settings

first of all you need a EntityDataAccessor for the size similar to the Slime define the EntityDataAccessor in #defineSynchedData via SynchedEntityData#define then create a method which sets the value of the EntityDataAccessor inside the method you also need to call #reapplyPosition and #refreshDimensions now to resize the Entity itself you need to override #getDimensions call super and scale the super value based on the EntityDataAccessor value this was the Entity part but you also need to change the Entity rendering inside your EntityRenderer you overwrite scale, im not 100% sure but i think you can simply scale the MatrixStack

post debug log

why on earth are you create there a new Thread, the most vanilla code is not thread safe thats why your BlockEntity is null this will also throw an Exception since you mix up server and client stuff, the Minecraft class is client only so you can not use it there, if you want to debug your code (because it looks like it) you should use a Logger last but not least you should use the Java Naming Conventions (method names)

make sure the log you post was the full log, since it's simply ends if it was the full log, please post launcher log

this is not possible, please show the full code

take a look at the first post in this thread

show this method please

show your Mod main class and the Entity registry

this is your error

show your code

Blocks do not have any NBT data, they have onyl the BlockStateProperties, what did you mean by change?

is the position load?
