Your problem is the ScudMissileMod trying to load client classes on the server. The mod author no longer supports that mod: https://www.curseforge.com/minecraft/mc-mods/scud-missile-mod and minecraft 1.12 is also no longer supported in these forums.

Issue with quark. I don't see a version of that mod that claims to be compatible with minecraft 1.20 https://www.curseforge.com/minecraft/mc-mods/quark/files

Same issue, but different mods.

This issue has been asked many times before. Use the search function for possible solutions. It's basically some other mod breaking the game, but that midnight lib mod crashes the game when it happens. So you can't see the real error.

Issue with create, check you have the latest version then contact the mod author. But I would try without optifine first.

You don't need code or even a mod for that, you just need a datapack with a custom recipe file. Mods are automatically datapacks. Or you can create custom recipes with mods like Kubejs or Crafttweaker.

Not enough animations is one of those client side only mods that has been crashing servers for years.

One of your mods has a broken custom recipe. It is not being serialized to the network correctly. The error does not say which mod. Probably the only way you will find the mod for this kind of error is to experiment with removing mods until the problem goes away. Backup your world before removing mods. If the mod is not just totally broken (i.e. the mod developer never nested multiplayer), this kind of error usually indicates you have a mod for a different version of minecraft?

If that's really the full log, the real error will likely be in the launcher_log.txt Don't post logs in the forum please. Use a file upload site.

With a log that short, the error message is likely in the launcher_log.txt

The "conflict" is eureka not finding the mod valkyrienskies or at least not being able to load one of its classes

Check you have the latest version then contact the mod author.

atio6axx.dll is the AMD graphics driver. You need to contact AMD or your PC manufacturer/supplier for help if you can't get your drivers working properly. Or a specialised forum devoted to PC/AMD support might be able to help you?

I have underlined above mods that might be the cause of your problem? Check you have the latest versions then contact the mod authors. NOTE: Minecraft 1.16 is not supported in this forum beyond trivial problems.

Check you have the latest version then contact the mod author.

You can't have both jei and rei Also please don't post logs in the forum, use a file upload site. Also, also this question has been asked and answered hundreds of times before. Use the search function in future.

It looks like a custom recipe with a broken tag called "ore:plankWood" from the error message? That name reminds me of a pre Minecraft 1.12 ore dictionary entry rather than a modern item tag. 🙂

If what you are drawing is relatively static, i.e. doesn't depend upon dynamic data beyond things like the block properties in the BlockState, then you can create your own model loader: https://docs.minecraftforge.net/en/1.20.x/rendering/modelloaders/ This basically lets you setup most things at resourcepack loading time during the model bake. At runtime it will ask you for your quads (you should have prebaked these for each BlockState of your block): https://docs.minecraftforge.net/en/1.20.x/rendering/modelloaders/bakedmodel/#getquads https://github.com/MinecraftForge/MinecraftForge/blob/1.20.x/src/main/java/net/minecraftforge/client/model/IDynamicBakedModel.java#L35 This is not something I have ever done myself. I just know it exists. So I can't really help you with the details. Forge has a builtin OBJ model loader: https://github.com/MinecraftForge/MinecraftForge/tree/1.20.x/src/main/java/net/minecraftforge/client/model/obj and I know immersive engineering uses some custom models: https://github.com/BluSunrize/ImmersiveEngineering/tree/1.19.2/src/main/java/blusunrize/immersiveengineering/client/models

Please use the search function in future. These playsound FAQs have been asked and answered sooo many times before. https://forge.gemwire.uk/wiki/Sounds#Level You are doing 2.2 which assumes the sound has already been played by the client for any player passed in the first parameter. i.e. the player for ServerLevel.playsound is an "exclude this player".

Looks like you are missing the cloth config mod? But that webdisplays mod is not maintained: https://www.curseforge.com/minecraft/mc-mods/webdisplays If the original author won't support it, we won't/can't either.

Issue with snowrealmagic. Maybe a conflict with rubidum given the other information in that error?

Broken config file. If you don't have a backup of the file, delete it and it will be recreated with default values.
