The long version: * mixin is a tool used by mods to modify java bytecode. It is distributed with forge for the convenience of mod developers that use it, but it is not supported by forge. In fact, its use is discouraged. * the current version of mixin was released 4 months BEFORE java 18 so it will know nothing about that and later java versions https://github.com/SpongePowered/Mixin/releases * java 18 or 19 are no longer supported and neither will java 20 be supported once java 21 the next LTS (long term support) version is released sometime around September this year * java 17 is the current LTS: https://en.wikipedia.org/wiki/Java_version_history with support ending in 2027 or later The short version: Use java 17. Or alternatively, uninstall all the mods that use mixins.

Use java 17, mixin does not support java 20

And please do not post large files in the forums, use a file upload site.

Use java 17, mixin does not support java 20

The thing sending the incorrect data is on the server. So it won't be a client only mod.

The parameter you are passing is the wrong type. You can't post compiler errors here. This is a support forum not a teaching forum and especially not a teaching java forum.

Your client and server disgaree on what data an entity (a bat) has. The server thinks something is complicated data (NBT) while the client thinks it is a boolean. Probably the only way to find the mod causing the problem is to experiment with removing mods until the error stops happening. Backup your world(s) before removing mods.

Client side mod you don't need on the server.

Use java 17, mixin does not support java 20 And please don't post large files in the forum. Use a file upload site.

Level.explode() when on the server. e.g. look at the PrimedTNT entity

Isn't there a space in "Program Files"?

It's a file created when java hard crashes. https://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-VM/html/felog.html The top few lines has a summary of where it crashed. e.g. in the java virtual machine or your graphics card driver, etc.

Since this is a server config, it will be in world/serverconfig instead of the config folder.

https://minecrafthopper.net/help/exit-code/code-805306369/ You probably have a file beginning hs_err_pid in either your minecraft folder or launcher folder? If you do, just post the first 20 lines or so to see if that has some extra information. But I would guess you need to give it more memory.

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

Use the "issues" tab on curseforge: https://www.curseforge.com/minecraft/mc-mods/immersive-portals-mod You should research if it is already a known issue before duplicating bug reports. e.g.these are all the current "mod compatiblity" open issues for immersive portals: https://github.com/iPortalTeam/ImmersivePortalsMod/issues?q=is%3Aissue+is%3Aopen+label%3A"Mod+Compatibility"

If you are iterating over tags, you are almost certainly doing it wrong. Tags are meant as a kind of flag to say "does this object have this property". They can change dynamically, e.g. if somebody changes and reloads datapacks while minecraft is running. That means you should not do any preprocessing or caching based on their values at any one specific point in time. If you really want to do it. For a datapack registry it looks something like this: @EventBusSubscriber(modid = MODID) public class Test { @SubscribeEvent public static void listBiomesTagKeys(ServerStartingEvent event) { var biomes = event.getServer().registryAccess().registryOrThrow(Registries.BIOME); biomes.getTagNames().forEach(tagKey -> LOG.info(tagKey.toString())); } }

Then speak to the create mod authors. It is their mixin that is crashing when you try to view a map.

Conflict between apoli and obscureapi. Check you have the latest versions of these mods then contact the mod authors.

Something is taking too long on the server thread. You should have a crash report saying what the server thread is doing. There are lots of warning messages from valkyrenskies. Check you have the latest version of that mod then contact them.

Issue with valhelsia_core, others have said it conflicts with optifine.

Something is taking too long on the server thread. The only clue in that crash is it was doing something with block collision detection for a villager. That does not mean that was the cause. It's just what it was doing at the 60 second timeout. Try a mod like: https://www.curseforge.com/minecraft/mc-mods/spark to diagnose what is taking time on the server thread or otherwise stopping the server thread from progressing. Ask them for help if you can't figure out how to use it from their wiki.

These are the forge support forums. We can't fix other people's mods. Only the mod author can do that.

Looks like an issue with "imm_ptl_compat" whatever that is. Probably immersive portals, oculus or rubidium? Check you have the latest version of these mods then contact the mod authors. When you find out who it is, tell them to give their configuration files less ambiguous names so that others have a chance at debugging their broken mods.
