Here is the latest.log
All my mods work fine without this mod but when using this mod I cant even launch the game

Im not sure if you needed the latest.log or the crash log

Could you see if removing Optifine fixes the crash? I'm thinking Optifine mixins to the fog handling code so it'll conflict with SeeThroughLava

Yea, it did. I went back to using iris instead

This won't be compatible with Optifine as Optifine changes the fog
