How did he download it and where did he download it from?

It concerns me that you would rather install a random program to work around an issue rather than try to fix it.

This sounds a like an XY situation. Why do you want to debug using obfuscated names?

That makes no sense

Kinda telling someone to burn their house down because the faucet's leaking.

Try running it from the command line. What does it say?

Please read the installation instructions for your mods, you are missing a mod required by BetterFoliage

Please don't hijack other people's threads. Also, get the Installer, nothing else.

Twitch has a setting to use Native Launcher or Jar Launcher. You need to set it to use Native.

Why 1.14.3 specifically? Update to 1.14.4 and try deleting fml.toml from your config folder

Don't do that, especially when it reveals that you've made two threads on essentially the same topic

Don't post threads twice. Try the latest version of Forge 1.12.2

What's your GPU?

As it has been for years now, CurseForge should be your primary (if not only) source for mods, and yes there are already loads of mods for 1.14.4. As it stands right now Optifine's compatibility with Forge is a single preview version that targets an old beta version of 1.14.4 Forge, so no guarantees of compatibility with the newer versions. Running Optifine and Forge together (assuming you have compatible versions of both) is the same as it always was, put Optifine in your mods folder like any other mod.
