Crash at Forge 1.12.2

[Tabru]

So I wanted to install forge to play on mods, I went to forge website and installed the recommended version, setup went alright but when I launched Minecraft on Forge the log showed up with 30 warnings about being unable to find hash and assuming it's good or something. The Minecraft opened and right after closed without even showing the Mojang logo. It didn't even say the game has crashed, yet the crash report was made and here's what it says:

WARNING: coremods are present:
