Thanks. I will find another solution.

Can you tell me another solution?

Without Optifine also doesn't launch.

I'm using one of russian launchers. This launcher installed Forge itself, when it starts, it automatically adds Optifine to the Mods folder. But what is the game launch error?

Minecraft 1.12.2 ForgeOptifine crashes at launching (3/7) at item rendering. Help me, please!
