Mod conflictsSodium Crash: IllegalStateException: Worker threads are not running
What it looks like in the log
java.lang.IllegalStateException: Worker threads are not running
How to fix it
- Remove Not Enough Crashes (notenoughcrashes) from your mods folder, as returning to the menu after a crash leaves Sodium in an invalid state and masks the real error.
- Check .minecraft/logs/latest.log (scroll up to the earliest error) or older files in .minecraft/crash-reports/ to find the first crash that happened before this one.
- Restart Minecraft completely and trigger the crash again without Not Enough Crashes installed to see which mod actually caused the initial failure.
- Ensure Sodium and Fabric API (if on Fabric) are updated to the latest versions for your exact Minecraft release.
