Hello,
Whenever I try to launch my forge profile (forge-14.23.5.2855 with Windows Installer), an error occur immediately and re-open the Minecraft launcher, telling me that I have an Error Code 0.
I searched a bit and discovered that Optifine (OptiFine_1.12.2_HD_U_D1) was the mod who crashes my game... How and why is Optifine the mod that ?
I added my latest log file if it helps.
