It looks to be something related to twilight forest.

breaking in creative causes the client crash as well.

I have this fixed in dev, but try to set display item to something like one of the spawn eggs on chest, I have a suspicion that's going to crash with TF as well and there's nothing I can do there

Gold chests do not crash.

I have this Crashlog: https://bytebin.lucko.me/43MDXee26l

We also have had this issue happening but the chunk in which the crash has occured is now invisible when using Rubidium (& Oculus). I just don't know how to get my chunk back to load as even a server restart still makes the chunk invisible (still walkable and visible to other players)

Latest version on curserforge has the fix for this.
