Thanks for trying to help, I really appreciate it, but updating forge fixed the problem for me! I'm using 1.14.3 Forge-27.0.9 if anyone would like to know.

Twitch doesn't have its own launcher, when I press "Play" it opens the Minecraft launcher with the settings already in it like the directory and ram. Unless Twitch uses a modified version of the default Minecraft Launcher, I don't know what you mean by the Twitch launcher. Sorry if I'm just being a big noob.

This is what I found.

I have tried to follow your guide on getting twitch to run the game properly, however, in my pack's profile options, I cannot find any "GameDir" property. But if this is to direct the game to the right file, it is already there (for me it is C:\Users\<My User>\Documents\Curse\Minecraft\Instances\<My Pack's Name>\). And to clarify, I am also trying to play in Minecraft 1.14.3.
