Steps to Reproduce the Crash

Happens when I try and launch the game.
I'm running OpenSuse Leap, with Java 21.0.3.
And minecraft version 1.20.6
I'm launching the fabric version using the prism launcher but I don't think that should have any effect.
The only other mod installed is the fabric API.

I encountered the same issue when I downgraded to 17.3.0.51.

It's probably some fucky shit with my linux install, but I'm at a loss as to how to resolve it, a pointer in the right direction is all I'm looking for.

Thanks for the report!
You're trying to use an older version JEI on 1.20.6 but it's not compatible.
I only just finished the code for JEI on 1.20.6 today, it should be released soon.
