OK. Thanks!

Hi, i suspect you updated your Forge, right?
If so, check you Llibrary-1.7.17-1.12.2.jar coremod (it may cause trouble if outdated)

Also, check your OptiFine_1.12.2_HD_U_E3 to be new version.

 

I had same problem, and probably found sollution. Registered here just to tell you, if it's still relevant )

Optifine HD_U_E3 is only compatible with forge #2795, make sure you have the right Optifine version for your Forge version
