I am having an issue where I cannot open the Kiln menu at all. Is there anything I have to do in order to be able to?

I would like to add to this. Using charm-forge-1.16.5-2.3.2.jar while on Minecraft 1.16.5, you can't smelt clay blocks in terracotta in the kiln.

Playing through Engineer's Life 2 and am unable to access the Kiln. This has cause me to simply be stuck due to not being able to complete the task and move on. @dragos2332 were you able to find any solution?
