Edit: Tried latest kubejs too as of writing this (build.364), though no changes. Same errors.

I've been trying to find the cause of this error. Finally tracked it down. You can roll back to KubeJS 1902.6.0-build.142 to temporarily get around the bug. It seems to be a conflict between any 6.1 version of KubeJS and Silent Gear. Hopefully this gets fixed soon as it completely breaks loading any of the KubeJS server scripts.

Forget rolling back KubeJS. I found the fix on the KubeJS Discord after some searching.

Gnome on Discord said "Silent Gear doesn't allow the recipes even[t] to run asynchronously, which will result in an ConcurrentModificationException. To fix this, set allowAsyncStreams to false in kubejs/config/common.properties."

I tried it, and it worked for me!
