sxrrealism

hello. recently, i decided i should use 1.14.4 modded minecraft instead of 1.10.2, so i downloaded the lastest possible version of forge, along with some mods and booted up minecraft. it loaded up fine, and i made a new world. i had thought maybe minecraft was taking a little longer than usual to create and load the world, only for it to crash entirely. this is the log: ---- Minecraft Crash Report ---- // You're mean.
