Forge Crash with Optifine

Hey guys,

I placed "OptiFine_1.12_HD_U_C4" in my mods dir (I'm in the dev environment). The changelog for C4 states that it's compatible with #2387, however i still crash:

Hope someone can help me.

EDIT: I know tried it in the normal mc environment and it doesn't crash, however my whole ingame screen is just white and I can't see the world and my hand / item.

Bye!
