"The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from McLib (mclib)
EXIT CODE: -1"

You may need the crash report so here it is: https://pastebin.com/raw/bSM9tvCd

Thank you for your help @mchorse !

You have incompatible versions of my mods. Check compatibility table.

Also, just in case, if you were trying to get my Chameleon mod (animated Blockbench models), you downloaded wrong mod. The downloads are here. You'll also need GeckoLib 3.0 beta7 (it's Chameleon's dependency).
