Fabric ModResolutionException: Errors were found!

What it looks like in the log

net.fabricmc.loader.discovery.ModResolutionException: Errors were found!

How to fix it

1. Read the bulleted lines directly beneath 'ModResolutionException: Errors were found!' in your crash log—they name the exact mod that failed and the dependency or version it expects.
2. If the log says a mod requires a different version of 'Minecraft' (minecraft), replace that mod's .jar in your mods folder with a build matching your exact Minecraft version (note that older Fabric Loader versions sometimes print '1.17.x' when a mod actually requires 1.17.1).
3. If the log says 'Minecraft' or a mod requires a newer version of 'java' (for example, Java 16, 17, or 21 instead of Java 8), open your launcher's installation/instance settings and either clear the custom Java Executable path or point it directly to the required Java installation.
4. If a required dependency mod (such as Fabric API) is missing or has a non-matching version, download the matching version from Modrinth or CurseForge and place it in your mods folder.
5. Update Fabric Loader in your launcher profile to the latest stable version, as older 0.11.x builds can display misleading version ranges in resolution error messages.
