You have mods with duplicate mod ids probably because they are different forks of the same project. Usually jei (just enough items) and rei (roughly enough items) or jade and wthit - both forks of waila.

You are correct, it is a java question. You appear to be using an unsupported (in this forum) version of forge, I think 1.12? But then trying to use api that is from forge 1.19, e.g. import net.minecraftforge.fml.common.eventhandler.SubscribeEvent; // <-- 1.12 import net.minecraftforge.eventbus.api.SubscribeEvent; // <-- 1.19 RegisterEvent was introduced in 1.19

This is a crash within the java virtual machine - jvm.dll. You should report it on the link it shows. Looks like it has a problem reading one of the jar files and didn't handle the error properly. You can try a different version of java, such as: https://adoptium.net/ It might at least give you a better error message about the problem?

Issue with the calio mod. Check you have the latest version, then contact the mod author.

Issue with flywheel. Check you have the latest version then contact the mod author.

Conflict between iris and oculus. Check you have the latest versions then contact the mod authors.

You have mods that want a different (probably later) version of forge, try the latest version.

You are trying to use a 1.19 mod with minecraft 1.18.2 You're actual crash is with the tetra mod: Check you have the latest version then contact the mod author.

Looks like one of your mods has broken networking. The error message does not say which one. Probably the only way you will find it is to remove mods one-by-one until the problem goes away. If you are just starting with modded minecraft, I would suggest you use a prebuilt popular modpack that somebody else has tested They should have already removed all the bugs and incompatiblies. Otherwise you are going to spend a lot of time trying to do it yourself.

Upgrade your java. The version you are using has expired trust certificates.

Post a link to your logs/debug.log

Issue with the flywheel mod. Check you have the latest version then contact the mod author.

You know when you create a falling block the actual fall will be delayed to later processing? So, it could be you are setting the block to air, then on a later tick the block is failling and creating the source block. Setting the block to stone would likely stop the falling block from creating the source block? Probably it tries to spawn the ItemEntity drop for water which doesn't have one.

That effectively uses LiquidBlock.pickupBlock() - assuming you are dealing with a LiquidBlock? That calls setBlock() with flags = 11 while setBlockAndUpdate() calls setBlock() with flags = 3 Which means it is setting the "UPDATE_IMMEDIATE" flag as well - see the Block class. I don't know what difference that makes? It's not a flag I am familiar with.

Sorry, that should be iris and oculus.

We want the logs/debug.log which will contain any error if there is one. Crash or otherwise. But it sounds like you have something looping on the server thread? To diagnose that we need a thread dump: https://www.baeldung.com/java-thread-dump Or maybe the spark mod will tell you which mod is consuming a lot of time on the server thread: https://www.curseforge.com/minecraft/mc-mods/spark

remove/destroyBlock() don't remove the fluid . Did you look at the code? Those methods are intended for things like breaking a waterlogged fence post. It will remove the post but leave the water behind. Try doing something like: Level.setBlockAndUpdate(pos, Blocks.AIR.defaultState());

Issue with debugify mod. Check you have the latest version then contact the mod author.

Issue with valhelsia core. Others have said it is known to conflict with optifine.

Conflict between iris and rubidium. Check you have the latest version then contact the mod author.

Not a 1.19.2 mod.
