as fweo already said you Log must be in the vanilla logs tag, this will fix your problem. if you not have any kind of Log you need to set the persistent BlockStateProperty to true when the Block is placed or you need to override #tick in your Block class

if your Menu is bind to a BlockEntity you can get the Position from it pass in the BlockPos into the server side constructor (the client need a dummy BlockPos), when you then create your Menu in the BE you can use the position which is stored in it. if you're not using a BlockEntity you need to do the same but set the position when you open the Menu by your self

ForgeRegistries.<the IForgeRegistry you need>.getKey, if there is no ForgeRegistry for the registry entry you can use the vanilla Registry Correction: I misread the title (get != set), see answer of D7

try null instead of a new BitSet inside the ClientboundLevelChunkWithLightPacket constructor if this does not help post debug.log

in the CurseForge settings

Have you done this? If yes please post debug.log from server and client

Remove Optifine.

create an EventHandler as you have done it for all other events, inside FMLClientSetupEvent you need to use #enqueueWork since Screens are not thread safe

All logs you post do not contains any error which cause the game to crash. If this is the full debug.log please post launcher_log.txt as well
