I had the same issue, for me it occured when using industrial block on a large cogwheel. I had to remove the mod and reload the game to make it disappear. Else, every time I launched the world I crashed immediately.
I am using embeddium, but the game crashed even without it.

Same problem with industrial large gear here.

Same problem here, specifically with the industrial cogwheel.
Recommend not updating the mod until this is adressed.

fixed

Where can I find the branch/tag of the 0.3.0 version of MC 1.20.1?
I was going to make a temporary fix but it seems that every branch is either to far ahead (on 1.19) or to far behind.
