So I downloaded the Test Datapack and Resourcepack and added them to my game, which did work since the machine is there and showing fine but when i place it and open the GUI it will open but immediately freeze the game and then crash.

Forge Version: 40.1.25 on MC 1.18.2
Mod Version: 1.18.2-0.6.0

Fixed in latest version (1.18.2-0.6.1)

Look like I used a class from kubejs instead of the one from mc without noticing... So the mod won't work without kubejs installed (on at least the machine gui).
Thanks for the report I will fix that soon.
