The game crashes on startup and doesn't provide a pop-up or crash report. I'm running 1.12.2-forge-14.23.5.2854 through the normal Minecraft launcher. Both BP and Forgelin are present. The game starts and runs normally without these two mods but crashes on startup with these mods present.

The Minecraft launcher open output log displays this when I attempt to start the game:
MinecraftGameOutput.txt

I also got this fatal message from the game output when trying to start the game again with the same mods (including BP and Forgelin):
Process crashed with exit code 1

I noticed these lines in the output:
[22:40:26] [main/FATAL] [FML]: A CRITICAL PROBLEM OCCURRED INITIALIZING MINECRAFT - LIKELY YOU HAVE AN INCORRECT VERSION FOR THIS FML 22:40:26.483 [22:40:26] [main/ERROR] [LaunchWrapper]: Unable to launch

I'm not sure what to do with the info from the above lines. If I should post on the Forge Forums, please just say that.

Thank you for any and all help.

Edit1: I removed Optifine and launched, game still crashed on startup

Having same problem, is caused by VanillaFix, please patch I can't remove VanillaFix for it is used almost every time the game is loaded.
