Installed Forge from the Twitch Client for 1.12.2 and the game crashed as when launched

As the title says, I installed a fresh profile with Forge on 1.12.2 (without any mods yet so I could check if it works) and when I go to launch it, it crashes. I disabled the splash-screen in the .minecraft/configs folder but the problem still persists. Here's what latest.log has to say.
