you already done it

did you register the DeferredRegisterin the constructor of your main Mod class (see: https://forge.gemwire.uk/wiki/Registration#DeferredRegister)? as i already told you, you can not store data like this in your Item class since it's a singleton the Item exists once, you need to use the Tag data of the given ItemStack or for more complex data a Capability you can not do this, vanilla is in the most areas not thread safe, if you want a delayed task you need to use a TickTask you can take a look at ForgeInternalHandler EntityJoinLevelEvent fro an example

AttributeModifiers are add to the MobEffect not the MobEffectInstance

it's in .minecraft\launcher_log.txt if you using CurseForge it's in curseforge\minecraft\Install\launcher_log.txt

do this

you need to set the potion via NBT data, i would recommend to use Data generation for it you can set the Potion of an ItemStack with PotionUtils.setPotion Note you need to use StrictNBTIngredient instead of the vanilla Ingredient, since the vanilla Ingredient does not check the tag (nbt) data

then you need to wait for updates or downgrade Forge

the correct way would be BlockState#is with BlockTags.LEAVES, but GLMs do not use Blocks, in this case it would be ItemStack#is with ItemTags.LEAVES

do you mean a Block in the world or a BlockItem, please give us a bit more content

you can use ServerChatEvent

please post debug.log on CurseForge you need to enable the debug.log in the settings

please post debug.log from the logs folder

it's a file which is generated by the installer, you find it in the same folder where you run the installer

please post debug.log from the logs folder

please post debug.log from the logs folder

please post debug.log from the logs folder

yes it's the correct log but it does not show any error which crash the game but i would guess you have the same error as most people playing on 1.19 Forge has had breaking changes recently, mods need to update for them. Check if there are updated versions of your mods or downgrade Forge.
