I've been trying to install tis certain version of forge, but everytime i try to play it crashes on installation. ive deleted and redownloaded the version and files in the forge file (libraries/net/minecraftforge) but nothing works. ive also looked for a similar thread, but it was closed before the issue was actually resolved, the link being https://www.minecraftforge.net/forum/topic/67871-minecraft-forge-1122-crashes-on-startup/

This topic is now closed to further replies.

Failed to load resource META-INF/jarjar/metadata.json

Hello, i'm trying to launch a server with additional mods i've added myself, and it isn't launching - but scrolling through the debug.log i came across [main/TRACE] [net.neoforged.fml.loading.moddiscovery.locators.JarInJarDependencyLocator/]: Failed to load resource META-INF/jarjar/metadata.json from MixinSquared-0.2.0-beta.6.jar, it does not contain dependency information. which came up a lot - im just wondering if this could be why my server won't launch

made a modpack but i get this error every time i try to launch minecraft

[main/ERROR]:Failed reading REFMAP JSON from : java.lang.NullPointerException Cannot invoke "org.spongepowered.asm.mixin.refmap.ReferenceMapper.setResourceName(String)" because "mapper" is null

this is the error message i keep getting when trying to launch minecraft from the launcher with my mods but i just can't figure out what this error message means. i'm new to making mod packs but i have tried making 3 separate mod packs with different mods but i still run into this issue and i am starting to think there might be a conflict between 2 different mods but again i have no idea since this is the only error message i get. any idea's?

The game crashed: rendering overlay Error: com.electronwill.nightconfig.core.io.WritingException: An I/O error occured

Add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

i have downloaded a mod called All in One (Modded One Block) and downloaded it through essentials mod to play with my friends, it starts to load up and start loading into the game but then i get the crash report and get sent back to the launcher with the error code "The game crashed: rendering overlay Error: com.electronwill.nightconfig.core.io.WritingException: An I/O error occured".
