reeeeeee

I go to the Minecraft launcher (1.14) to load up 1.12.2 Forge. (there's a specific, unupdated mod.) When I select the Forge version, the green bar is finished loading, and the launcher disappears, then...nothing. It says Java is running in the background, but nothing appears. I've waited up to an hour. I am using version 2768, the recommended version. I'm on Windows 10. This is the log: [19:55:59] [main/INFO]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [19:55:59] [main/INFO]: Using primary tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [19:55:59] [main/INFO]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLTweaker [19:55:59] [main/INFO]: Forge Mod Loader version 14.23.5.2768 for Minecraft 1.12.2 loading [19:55:59] [main/INFO]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_51, running on Windows 10:amd64:10.0, installed at C:\Program Files (x86)\Minecraft Launcher\runtime\jre-x64 [19:55:59] [main/INFO]: Searching C:\Users\Student\AppData\Roaming\.minecraft\mods for mods [19:55:59] [main/INFO]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLInjectionAndSortingTweaker [19:55:59] [main/INFO]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLDeobfTweaker [19:55:59] [main/INFO]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLInjectionAndSortingTweaker [19:55:59] [main/INFO]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLInjectionAndSortingTweaker [19:55:59] [main/INFO]: Calling tweak class net.minecraftforge.fml.relauncher.CoreModManager$FMLPluginWrapper [19:56:01] [main/INFO]: Found valid fingerprint for Minecraft Forge.
