I've been trying to install forge, better sprinting and optifine, but i can only seem to be able to install one of them or else the game crashes. For example if I install Forge alone it will work, but if I try to install Forge with Better sprinting, the game will crash. The game crashes no matter what combination I try to instal (Forge-Optifine, Better sprinting-optifine, optifine-forge, etc). If somebody has a solution or if its a bug please let me know.

I put the dev console when trying to install better sprinting and optifine:
Thanks
