Debug Crash Log

.

Same issue here.

Somewhere between 1.19.2 and 1.20.1 Mojang changed part of the id names for armor:
head - helmet
chest - chestplate
legs - leggings
feet - boots

To fix this you would need to make rename the 8 pieces of armor like so:
item.immersiveengineering.armor_steel_head - item.immersiveengineering.armor_steel_helmet
And so on.

There is a similar issue with the Engineer's Toolbox in the same version. The block is called block.immersiveengineering.toolbox_block where the language files have it as block.immersiveengineering.toolbox. I came here to report the armor and the toolbox. Hope adding this here is ok.

Malte already fixed the armors in a previous commit.
I've now also fixed the toolbox.

Next release will see this resolved.
