You are missing the smartbrainlib and modonmonicon mods or have the wrong versions for the mods that want them installed.

I believe the data it is complaining about is in the main level.dat file, but as I said I have never done this. You need an nbt editor to modify it, but you also need to know what you are doing otherwise you will break the whole save. If you do choose to modify it, back it up first!

The first log shows the client is losing its connection. I can't see the reason in that log. It's not due to initial connection timeout. e.g. in the last one it is 30 seconds after the player notionally joined the game. The second log seems to be an due to an error? Just before the player is disconnected they are getting a message about invalid data. For the first problem, you need somebody who can help you understand why that player is losing its network connection. It's not me 🙂 I would guess it is related to that player's computer struggling to keep up with running the game given how long it takes to make the initial connection (70 to 90 seconds)? The second problem looks to be a bug in a mod or maybe some mismatch in what the client has installed/configured versus the server. There are warnings from journey map at the same time about missing textures related to entities which might give a clue to which is the problem mod? I would suggest to start with getting that user to reinstall the modpack to make sure they have the right mods, versions, etc.

Issue with valhelsia_core. Others have said it conflicts with optifine.

I would backup them up first in case one of the mods is misusing the config file to store real data in someway.

If you have such a filesystem, the file size will be misleading. You could try something like wc -c * if you are using a un*x. It prints the "byte count" for every file in a directory. System admin commands are not really my expertise. 🙂

That's what I said above and why I quoted "empty" above. Some OSes allocate a certain amount of space for a file even if it is empty.

It depends how your OS reports file sizes. But probably, yes.

Look at the file sizes in the folder. If the OS failed to save the file it is usually "empty".

One of your mods has a broken/corrupted config file. You can find it world/serverconfig If you don't have a backup of this file, delete it and it will be recreated with default values. The usual cause of this problem, is your computer not shutting down properly (e.g. power outage) which means file changes are not flushed to the physical disk by the operating system. Forge updates the config files everytime you boot the game to make sure the files have all the latest config options specified by the mods.

Download the latest optifine preview release for 1.18.2

There's over a thousand examples on github. Find one that is up-to-date and suites your taste and what you are trying to do. https://github.com/search?l=Java&q=BlockEntityWithoutLevelRenderer&type=Code

There is no real error in that log. If it is the full log, post a link to the launcher_log.txt before restarting the launcher.

You should remove the broken client side only mods from the server. Or contact the modpack author or mod authors for help.

Something is taking too long on the server thread. When it crashes it is doing something with datafixupper for a structure. The most direct reference to modded code is betterstrongholds and quark mixins. But the actual thing causing this worldgen code to trigger is some pathfinding within Alexsmobs I suggest you install something like the spark mod to get more accurate information about what is taking time on the server thread than the above snapshot. https://www.curseforge.com/minecraft/mc-mods/spark Then contact the relevant mod authors.

Issue with alexsmobs, check you have the latest version then contact the mod author.

You have a number of broken mods trying to load client side classes on the server. Most of them look like client side only mods you don't need on the server?

Use java 17. Mixin does not support java 19

If you deobfuscate the jar at runtime it will just break everything. Instead you need to obfuscate whatever it is you are doing like ForgeGradle does with the reobfJar task These are the mappings from minecraft's obfuscated names to forge names (for 1.19.3) https://raw.githubusercontent.com/MinecraftForge/MCPConfig/master/versions/release/1.19.3/joined.tsrg To get from mojangs official mappings to its obfuscated names, requires the use of the MojMap files (again 1.19.3) https://piston-data.mojang.com/v1/objects/42366909cc612e76208d34bf1356f05a88e08a1d/client.txt https://piston-data.mojang.com/v1/objects/bc44f6dd84cd2f3ad8c0caad850eaca9e82067e3/server.txt To work out which mappings to use requires downloading the main version manifest to get the specific version file https://piston-meta.mojang.com/mc/game/version_manifest_v2.json https://piston-meta.mojang.com/v1/packages/6607feafdb2f96baad9314f207277730421a8e76/1.19.3.json then looking in that for the client/server mappings elements.

If you have any mods that use mixin, it doesn't support java 19. Use java 17

Rubidium is trying to load client side classes on the server. You don't need rubidium (a client side only mod) on the server.

Same error as I posted above: You should check whether a mod has a dependency when you download it, e.g. https://www.curseforge.com/minecraft/mc-mods/just-mob-heads/relations/dependencies
