Fabric ModResolutionException: Mod resolution failed!

What it looks like in the log

net.fabricmc.loader.discovery.ModResolutionException: Mod resolution failed!

How to fix it

  1. Scroll down to the 'Caused by:' line in your crash log to check whether it says 'Failed to open mod JAR' (unreadable or corrupted file) or 'Failed to turn path ... into URL!' (incompatible custom launcher).
  2. Update Fabric Loader in your launcher profile to a modern version (0.12.0 or newer, latest recommended), which replaces the legacy URL scanner that fails on custom and mobile launchers.
  3. If the 'Caused by:' line points to a specific mod JAR, delete that file from your mods folder and download a fresh copy from Modrinth or CurseForge.
  4. If every mod fails to load on a custom client launcher or PojavLauncher, update PojavLauncher and its Java runtime, or switch to a standard launcher such as Prism Launcher or the official Minecraft Launcher.
