I keep getting that crash report and I do not know what is the cause of it. Earlier today my server was running just fine until I restored a backup, and now it's crashing like crazy. Before this crash report, my server was crashing due to crash-report ServerHangWatchdog detected that a single server tick took 60.00 seconds (should be max 0.05), which I fixed by disabling watchdog. I'm running Valhelsia 2 on my server and it contains 157 mods.

Please post your debug.log, using a paste site like Pastebin, Hastebin, paste.gg, or GitHub Gists.

It's a very long log. Sorry for the late reply

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Logs (Most issues require logs to diagnose):

Reveal hidden contents

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/: 100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

A file sharing site would probably be necessary depending on the size of the file.

Did you wipe the world folder before restoring the backup? I'm not getting the issue.

I went into the Atum dimension which broke the server (before the server started crashing). I then wiped the world folder and then copied the most recent backup and pasted it into the world folder. It worked fine for a bit then started crashing a lot.

  Veuillez lire la FAQ (le lien est en haut de la page) et les journaux de publication tels que décrits ici. Cela aidera à déterminer ce qui se passe. Ce sont des forums anglais, j'ai utilisé un traducteur pour essayer de vous aider, j'espère que ça se retrouve bien.
- [1.20.1] Modpack crashing on startup - Mod not loading correctly
  
  By SeniorDee · Posted 2 hours ago
  
  I tried adding the Create (6.0.4) mod to my modpack which causes it to crash before it finishes loading. I tried removing the mod Cold Sweat because the error said it failed to load due to something in Create but when I removed it, it kept crashing; and I also tried downgrading Create, but nothing helped. I assume there's an incompatible mod that's causing Create to not load correctly, but I can't find it. launcher_log.txt: https://mclo.gs/kn5Qkk2 debug.log: https://mclo.gs/zIKoAaB crash report: https://mclo.gs/j86C10Y The part of debug.log that I think is the crash (after Create mod already loaded incorrectly): [02May2025 14:52:36.813] [Worker-ResourceReload-2/ERROR] [net.minecraftforge.fml.javafmlmod.FMLModContainer/]: Exception caught during firing event: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour Index: 3 Listeners: 0: NORMAL 1: net.minecraftforge.eventbus.EventBus$$Lambda$1770/0x00000008009bc8a0@70223c71 2: ASM: class com.momosoftworks.coldsweat.core.event.PotionRecipes register(Lnet/minecraftforge/fml/event/lifecycle/FMLCommonSetupEvent;)V 3: ASM: class com.momosoftworks.coldsweat.compat.CompatManager$ModEvents setupModEvents(Lnet/minecraftforge/fml/event/lifecycle/FMLCommonSetupEvent;)V java.lang.NoClassDefFoundError: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour at TRANSFORMER/cold_sweat@2.3.12/com.momosoftworks.coldsweat.compat.CompatManager$ModEvents.setupModEvents(CompatManager.java:501) at TRANSFORMER/cold_sweat@2.3.12/com.momosoftworks.coldsweat.compat.__ModEvents_setupModEvents_FMLCommonSetupEvent.invoke(.dynamic) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:73) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.EventBus.post(EventBus.java:315) at MC-BOOTSTRAP/net.minecraftforge.eventbus/net.minecraftforge.eventbus.EventBus.post(EventBus.java:296) at LAYER PLUGIN/javafmllanguage@1.20.1-47.4.0/net.minecraftforge.fml.javafmlmod.FMLModContainer.acceptEvent(FMLModContainer.java:121) at LAYER PLUGIN/fmlcore@1.20.1-47.4.0/net.minecraftforge.fml.ModContainer.lambda$buildTransitionHandler$5(ModContainer.java:127) at java.base/java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1804) at java.base/java.util.concurrent.CompletableFuture$AsyncRun.exec(CompletableFuture.java:1796) at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:373) at java.base/java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1182) at java.base/java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1655) at java.base/java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1622) at java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:165) Caused by: java.lang.ClassNotFoundException: com.simibubi.create.content.redstone.displayLink.DisplayBehaviour at cpw.mods.securejarhandler/cpw.mods.cl.ModuleClassLoader.loadClass(ModuleClassLoader.java:141) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:525) ... 14 more [02May2025 14:52:36.972] [Worker-ResourceReload-2/ERROR] [net.minecraftforge.fml.javafmlmod.FMLModContainer/LOADING]: Caught exception during event FMLCommonSetupEvent dispatch for modid cold_sweat java.lang.NoClassDefFoundError: com/simibubi/create/content/redstone/displayLink/DisplayBehaviour at com.momosoftworks.coldsweat.compat.CompatManager$ModEvents.setupModEvents(CompatManager.java:501) ~[ColdSweat-2.3.12.jar%23537!/:2.3.12] at com.momosoftworks.coldsweat.compat.__ModEvents_setupModEvents_FMLCommonSetupEvent.invoke(.dynamic) ~[ColdSweat-2.3.12.jar%23537!/:2.3.12] at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:73) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.eventbus.EventBus.post(EventBus.java:315) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.eventbus.EventBus.post(EventBus.java:296) ~[eventbus-6.0.5.jar%2387!/:?] at net.minecraftforge.fml.javafmlmod.FMLModContainer.acceptEvent(FMLModContainer.java:121) ~[javafmllanguage-1.20.1-47.4.0.jar%23784!/:?] at net.minecraftforge.fml.ModContainer.lambda$buildTransitionHandler$5(ModContainer.java:127) ~[fmlcore-1.20.1-47.4.0.jar%23783!/:?] at java.util.concurrent.CompletableFuture$AsyncRun.run(CompletableFuture.java:1804) ~[?:?] at java.util.concurrent.CompletableFuture$AsyncRun.exec(CompletableFuture.java:1796) ~[?:?] at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:373) ~[?:?] at java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1182) ~[?:?] at java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1655) ~[?:?] at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1622) ~[?:?] at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:165) ~[?:?] Caused by: java.lang.ClassNotFoundException: com.simibubi.create.content.redstone.displayLink.DisplayBehaviour at cpw.mods.cl.ModuleClassLoader.loadClass(ModuleClassLoader.java:141) ~[securejarhandler-2.1.10.jar:?] at java.lang.ClassLoader.loadClass(ClassLoader.java:525) ~[?:?] ... 14 more

  You would probably be better served looking for support where NeoForge support is given, I believe their discord server.

  If you copy and paste the java commandline into the terminal, what happens? as in trying to launch it without using the .bat file.
