The game crashes the instant I try to open the mods config menu.
Minecraft: 1.12.2
Forge: 14.23.5.2860
Inventory Bogo Sorter: 1.0.3
ModularUI: 1.0.2
Crash Report: https://pastes.dev/gTHst3tEqz

Side note: Translation key for the key binds was not set, so they look really strange.

I uploaded new version of ModularUI (1.0.3) that should fix it
