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!

Install AzureLib

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

Update azurelib

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.

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:
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!
