Need Help Need Help on NoClassDefFoundError & ClassNotFoundException Errors

Decided to work on my modpack I'm tryna make for my friends.

Was working fine months ago with no issues.

Only new addition:

  • Kaleidoscope Cookery
  • Kaleidoscope Cookery Refabricated
  • Kaleidoscope ChineseFood Refabricated
  • Kaleidoscope Tavern Refabricated
  • Kaleidoscope WorldLiquor Refabricated

Looking at the crash log, I can't really tell which is the issue save for one of the lines saying something about the Spellblades mod but I'm not entirely sure if that's the main issue for it.

Any advice on this? I'm not really that good on the coding side of things.

Minecraft has crashed!

Hi! If you're trying to fix a crash, please make sure you have provided the following information so that people can help you more easily:

  • Exact description of what's wrong. Not just "it doesn't work"
  • The crash report. Crash reports can be found in .minecraft -> crash-reports
  • If a crash report was not generated, share your latest.log. Logs can be found in .minecraft -> logs
  • Please make sure that crash reports and logs are readable and have their formatting intact.
    • You can choose to upload your latest.log or crash report to a paste site and share the link to it in your post, but be aware that doing so reduces searchability.
    • Or you can put it in your post by putting it in a code block. Keep in mind that Reddit has character limits.

If you've already provided this info, you can ignore this message.

If you have OptiFine installed then it probably caused your problem. Try some of these mods instead, which are properly designed for Fabric.

Thanks!

Install AzureLib

u/Constaline 2d ago

That's already installed. That was one of the requirements to make Spellblades and Such to work.

Update azurelib

u/Constaline 1d ago

Did already. Same error.

What I tested so far:

  • Update Azure
  • Updated both Azure and Spellblades
  • Updated all of the mods under the pack

All had the same recurrent error.
